iPhone 6s constant sign-in required
Running iOS 11.2.2 Continually getting a dialogue box that says:
"Sign-in required. Enter the password for [my apple ID]
[entry box]
Cancel. Continue"
It doesn't matter if I hit Cancel, or enter my password and continue. I can access apps either way. But it is very annoying.
Usually happens after iPhone is asleep, but sometimes happens anyway.
Any solutions? I had this problem before and reset the iPhone. That helped for a little while, but the problem is now back. I upgraded from 11.2.1 to 11.2.2. No resolution to problem.
