@Jake Rill Trello recently made some changes to make attachments more secure and a side effect of that has been that things automatically download rather than preview. Here's the official statement from the team that I think explains it quite well:
We recently made some changes to how attachments are secured, largely to make sure they’re kept private. Anytime loading an attachment now, checks are made that the person has the board permission to view that attachment, so generally speaking, a good thing. The unintended side effect is that it also made some changes to our preview service, so moving forward, only images and videos will be able to be previewed.
This card from Trello’s Platform team has more details on how this works: https://trello.com/c/tnX5dhiI/87-updated-authenticated-access-to-s3
It may help to upload files via third-party service (i.e. Google Drive) if attachment previews are needed for your use-case.
With all that said, I’ll add this ticket on our feedback board for our product team as right now they’re aware that previews are no longer available mostly because of a technical limitation. I’m not aware of any plans to change this for the moment but I’ll pass the feedback nonetheless!
I understand the security issue being addressed and I appreciate the quick response and the appreciation for our issue. We are all a bit worried at my company so I hope this is a priority and can be fixed soon. While I do hope to see a preview function again, when PDFs opened in a new tab to view, it was at least workable, but it is definitely broken when it makes me download PDFs to view them. And then I have to delete them right after viewing. It’s alarmingly cumbersome to our usual workflow. At this point I feel like I’m kicking a dead horse so I’ll just say thank you again for the quick response and passing this along.
@Brittany Joiner For better or worse, I use Trello as a de-facto means of file organization. I don't have the time to re-save every .PDF on our Trello board to Google Drive or Dropbox as a workaround. Without exaggeration, I am near tears with frustration. My team's productivity has plummeted due to this update.
The Atlassian team may see this update as a net positive from a security perspective, but PLEASE understand how terribly this is affecting the usability of your platform. My small business runs on Trello; usability is not an abstract parameter here - this is costing me money every day it is not fixed. I'm begging for a means to preview .PDFs without downloading.
We keep our attachments on Trello so all our members do not have to download to their personal computers and we prefer it that way for privacy reasons. Uploading to Google presents the same issue unless we use Google's Workspace $$ in addition to paying Trello and it requires multiple steps for each upload in addition to creating and adding the attachment. This is definitely a downgrade at a time we are paying more for the Trello service. This is not the first time Trello has downgraded existing services to allow for upgrades we must pay for additionally.
This needs to be fixed ASAP. These types of changes can’t happen like this. Granted I don’t know anything about programming, but this worked for 2 years and all of a sudden it’s broken. Go back to the old way until a better solution is found. This security fix can’t be necessary with such a serious side-effect. This beautiful platform is absolute trash without reliability. Why Trello? I am forced to start looking at other platforms today unless I get immediate transparency on this issue. Either go back to the way it was YESTERDAY MORNING, until a better solution is found. Or I will even accept if they tell us to chill out, this is an easy fix, will be fixed by today or Monday morning. No chill right now. Better security is not worth this.
I to must complain about this downgrade after the last official "update". Trello of early 2021 was working perfectly and was the "go to" tool. Trello of August 21 and later is a slowly coming disaster. First, link to files without login was a HUGE plus for our organization for approval of design files. That is gone. Now, preview of PDF or Excel files is gone and downloading each file is a big step back. If you are concerned about security, suggesting the use of third party, like Google drive, is not a solution - why I would want to spread all my files across multiple services when I was able to have them only in one? Does not seem like a security update!
What a pity. This was a such a perfect tool! No longer.
I am completely frustrated as well! Trello preview for pdf and docs is one of the central features of Trello. The idea of having everything centralized in one tool is the core beauty of Trello. Cmon Trello, why did you go and break the best feature of the app? Trying to stay optimistic that you listen to the people and fix the problem so we can continue to be super fans!
Echoing the frustration others have voiced. This changes has very negative impact on workflow. Centralized location of relevant assets (images, PDFs, Microsoft Office files) was a key benefit of Trello. Now the same file ends up needlessly taking up space on all team member's machines. If If I need to quickly refer to an old version, I'm going to have to download it again to make sure I'm looking at the right one. Please find a solution that maintains the security requirements on Trello's and users need to preview without downloading.
Also coming hear to voice my frustration with this change. This has made things wildly more time consuming and downloading all of these documents on my computer is taking up unnecessary space that I then have to go and delete each time after I use Trello! Ughhhh!!! Please put it back to how it was before!!
I came here with the same question. It is really annoying to have to download the documents every time you need to check some information, especially if you use trello as a backlog. They should at least give you the option to return to what it was before.
It feels like every update on Trello is for the worse. Like they have fired all the designers and the programmers have taken over.
But then for every file I would have to put it on Drive, and then link it to Trello. I would also have to organize the files on Drive, and not only on Trello. It's not practical at all.
Also, if the issue is security, why would I give Trello access to all my files on drive?
@Brittany Joiner the reason we got the "upgrade" is that Trello became more secure. What kind of security update it is if you recommend to fracture your storage across to different services, so in addition of using, supposedly now more secure, Trello, you want us to move some files to another services? What is the point of the storage on Trello, then? What kind of security is it if our files should be spread around? The point of Trello was to have a centralized tool that offered a cohesive solution and it WAS working for most of us. From security standpoint, we were even comfortable with the files access on Amazon servers - try to guess that link! That is also gone.
I am glad I am not the only one that misses the not "upgraded" Trello prior to August.
@Martin Purmensky the point is that if you are not concerned about security and more concerned with previewing your images, you could use those other tools.
I'm not going to post anymore on this thread :) Everyone here seems to have their mind made up that this is a must have feature and using other power-ups isn't desired, so I'm not sure I've got anything else valuable to add over here.
@Brittany Joiner What a disappointing a dismissive reply. You seem to be implying that usability and security are mutually exclusive features. Yes, many of us have "made up our mind" that we prefer a more usable version of the platform. Does this make us fools?
There is a community of users begging for a workable solution on this thread and many others like it. Can Atlassian not integrate a less secure, more usable option?
I have not seen a viable workaround mentioned in this thread. Is there, in fact, a power-up that provides a way to preview .PDFs without downloading them?
Hi Brittany, I realise that as a Community Lead you are not responsible for changes to Trello’s functionality and appreciate you taking the time to explain the situation and suggesting possible work arounds.
We, like many people, had a Trello workflow that was pretty slick and is currently a bit janky. I’m sure we will adapt.
I hope that our respectful feedback is passed on to the developers and that if this feature is requested (politely) by enough people the functionality may be returned in a future update.
@Robin and @Yucca Stuff sorry, didn't mean to come across as dismissive. Just hard when I see this and can't really do much about it, and I realize there's so much other stuff that makes Trello so good!
But yes, I've been sharing this thread with folks at Atlassian, they're very aware and trying to figure out what can be done here. Hope you all can understand it's not just a quick easy fix, but they're very aware and in my experience care a ton about user feedback, so this isn't something anyone is really trying to be dismissive of, but just can't take immediate action to solve. (Sorry, i know this doesn't help. and i do recognize this can be really disruptive to workflows.)
