issue with PDF previews in Trello

[Katarzyna Rogulska]

Hi, I’ve run into a strange issue with PDF previews in Trello and I’d like to report it as a bug.

I’m attaching an example file to show the problem.

On my computer I upload the new version of a PDF to a card (the old attachment is deleted first). When I open the preview of this PDF in Trello in the browser (Chrome and Edge on Windows), Trello still shows the old version of the file. However:

• when I download the attachment from the card, the file is correct (new version),

• in the Trello mobile app the preview is also correct (new version).

So the file stored on the server is updated, but the web preview in the browser appears to be cached and shows an outdated version. Hard refresh, incognito mode and trying another browser do not fix it.

Could you please check this behaviour?
