    My Android 9 MiNote7 phone keeps displaying a popup saying Authentication Error -- signin again. But it does not say where / how.. .. Is it an error for the phone or an app, in this case which? I have tried the phone's sig in on the LockScreen, and apps such as Outlook Mail, but the popup still appears. Suggestions?
