Blank screen only in game
When I start the game I just get a blank screen. This happens with either my phone or my old tablet. Ingress splash screen, but no globe and no game. "Power saving mode" still works: the Niantic logo appears if I invert the phone.
This must be an issue with my account, as my wife's old account still works on my phone, and it happens with two devices.
Prior to it happening, I did get some odd errors occurring, including an on screen error message around "action error" or something.
I can log into Intel ok.
I have tried clearing cache, then data, then deleting the app and reinstalling.
Device is Xiaomi Redmi Note 9S with Android 10, other device tried is the old Nexus 7. App 2.66.2.
Searching indicated that others have had a similar problem, but I couldn't find a solution.
