I have a really old iPad 2 running iOS 9.3.5. I use it with a dedicated weather app and it's the only app installed. Over the past few months now it's become an almost daily event that the Apple ID sign-on request is displayed. I enter the password correctly and it accepts it. And a day or so later here we go again. I have iCloud disabled and just about everything else disabled. All I need running is Wifi and this weather app. Are there any solutions to this?
