What happened to the preview option for attachment to boards?

[john]

We used to be able to click on an attachment and view it rather than it being automatically downloaded.

Hey @john - welcome to the Community. We've discussed this on a few different threads, but essentially, this change is in response to a browser security vulnerability, one that could have (but didn't!) compromise data integrity. Disabling PDF previews temporarily is our way of protecting your data; I know it's less convenient this way, of course, and I'm sorry about that. Image and video previews continue to work as before.

We don't have an ETA on when you'll see PDF previews again yet but it's one of our highest priorities. We need to make sure that when we enable previews again, it'll be secure.

thank you
