This bug may explain a few issues I have read about and encountered myself.
Today I was manually resetting a record in the sheet to a previous state by changing the values in the sheet. I clicked the manual Sync button and the value did not update in the app. Several attempts to re-Sync did not update the app.
Even launching the View Data shows the changed value but not in the view.
After some period of time and repeated Sync’s. The value will finally update.
This does not happen consistently but is happening frequently. Other apps do not appear to affected by the same issue. However, I have witnessed this very similar issue in the app of a client - a separate bug was opened for that.
