Our restaurant uses Sony TV's to display our menus and out of nowhere, they all went to the Google login in screen. When we log in it says it's successful but goes back to the enter password screen. We use an app to display the menu and when we just launch the app it goes back to the Google login screen after an hour or so. Any help would be much appreciated.
Could it be logging you out after inactivity? Idk honestly. Have you tried logging all devices out, changing your password maybe and trying it? Honestly I don't know a solution off hand
