Are you switching account providers? Say using Google sometimes and maybe Microsoft others?
I have recently discovered myself, that this message can be misleading.
If all your network connectivity is ON does indeed seem fine, then double-check that you are logging into the app with an allowed Authentication provider account. If so and still getting error. Try logging out and back in again.
