I attempted to create a bug card and upload screenshots of the bug. The screenshots I captured then cropped on my iPad Pro 11" uploaded as "zero KB" in size. Other users confirmed they are unable to see them.

I have the current version of the app as of 5/18/22. Tried deleting and reposting the card.
When I use a browser to access Jira instead of the app, it works. I can see the attachments there.
