Error: Table for this screen doesn't exist anymore

Hi, one my apps suddenly shows this error.

My data table is linked to a Google Sheet, all data is intact but when i opened it this morning all my work is missing.

Any idea how to resolve/restore this?

Have you tried a re-sync?

If you do that, and Glide complains about missing columns, then my advice would be to make a copy of the app first, check that the copied app reads all columns correctly, and then force a sync in the original.

I’ve tried to re-sync the app. Then, the columns did go missing.

But a few hours later, the columns did re-appear again.

I just realised even all my settings on the left side were missing.

Do you have any special configurations for the underlying sheet? Something like IMPORTRANGE?
