I’ve scoured the topics but found no match:
I just encountered an annoying bug(?) where I tried the checklist format, checked off the first four titles to see how it would look, went back to my sheet and saw that it had deleted the links (my only record) leaving only ‘FALSE’ in their places. I undid my app until it reached the point where I switched to the checklist format only to find it was grayed out and could undo no more. Same with my google sheet. I could not undo. Thankfully, I realized that I didn’t really want or need that sheet so I just conceded to the event. However, if it was important data that was irreplaceable, I would’ve been horrified.
For future reference, is it something that I did wrong? I am avoiding all checklists until then.
