It appears that items are not saving or following the one minute save rule.
These issues have occurred in date range cells as well as check box cells.
My thought is that this could be linked to a iOS 14 beta issue.
At this time, I have only noticed this occurrence with absolute certainty twice. Here is the current software that my iPad is running.
14.0 (18A5319i)
Any ideas? I have been using my ipad (using the full version) for a while, and never noticed any issues with the autosave. I checked my settings. Autosave is set for 1 min.
