Can't log in to iPhone with apple ID
When I go to settings, I am prompted to sign in to the Apple ID. When I try to do so, the little *just a moment* circle spins and then it just goes back to the log in screen as if nothing happened. No error message.
If I go to 'manage my Apple ID' on my PC, it shows I'm signed in on the iPhone. Also, I am getting apple ID verification code prompts on the iPhone when I try to sign in to apple services on my PC. This would indicate that I am signed in on the iPhone.
Both of these screenshots are from the same phone. How can I not be signed in with an apple ID yet still receive Apple ID verification prompts on the phone? Here's a shot from 'manage my Apple ID'. The iPhone on the far right is the device in question.
As you can see, even Apple Pay is set up on the phone, which surely requires my Apple ID be working.
I'm logged in on several iPads and on the PC (iCloud) with my Apple ID. What could the problem be?
