App Store keeps requesting sign in

I have found an answer to my App Store problem. Go to app store app tap on your initial (top right). Scroll right to bottom and log out. Scroll back to top and log back in. It worked for me after 3 hours of trying everything including an hour talking to Apple who ran out of ideas. No guarantees your problem is the same but it’s worth a try.

Not just me then. In fact I also have an old iPad mini. I’ve just tried that and it’s the same. I suppose we will just have to wait for it to be sorted. Thanks for responding.
