Is your device old? Or didyou recently update your iOS? Your General screen doesn't look like mine. I always wait at least 6 months after iOS comes out with an update to do so, I don't allow automatic updates. I wonder if the newest iOS is not compatible on iPad with the current CS software; remember, after iOS update, CS staff needs to check for compatibility, and then fix problems. I always told my clients NOT to update any software ASAP, then they never had problems when there were incompatibilities. I wonder if this newish spate of "unable to log in" correlates with the recent iOs update. Are you on iOS 12.2? I am not. Still on 11.2.6. The new update was supposed to fix (among other things) an issue in Settings > General > IPhone Storage , but since we are using iPads this update might glitch the iPad. The only update I do when it appears is the game itself.
