Weird bug I just came across working in the desktop app.
I was in a table view and clicked into the ‘Add Attachment’ dialog for a record. I had copied a URL of an image and was attempting to paste that URL into the ‘Link (URL)’ option. I hit CMD + V a few times with no luck having the URL paste. I then clicked out of the dialog to find the entire table I was working in had been changed to that URL. Every field of every record was that URL.
Luckily, I was able to hit CMD + Z a few time and we were back to normal. Very odd behavior.
