I am pretty new to PowerApps, but had a very good time building an app from a SharePoint Online list. I had started out thinking I needed a primary list with lookups to five other lists, but as I built the app, I realized it would be much simpler to have a single list (and SharePoint has a surprising small limit of lookups in any one list), so I started again, removing the fields that had used those multiple lists and lookups. I created a single list built from choice fields and completed building the app with that single list. The data is all in that one list, not coming from nor connected to those old lists at all. Everything worked great! ....
Until I decided to delete those old lists that I was not using. None of my fields in the screens and forms were connected to those old lists. But returning to PowerApps I now get an error reading:
The specified record was not found. Server Response: scrubbedSensitiveData
Apparently there is still some sort of connection to those old lists, but I'm not sure where (since there were no fields linked to those old lists). I tried restoring those lists, but that did not work because of the inter-list lookups that I had to remove before deleting those lists.
The code in the individual fields seem to still be showing the list name and field names, and the SharePoint site name and List name are still seen on the left pane when I click Data.
