The problem is believed to have started once the clock hit 12.15am on Saturday, December 2, in each respective time zone.
Update your device to iOS 11.2.
Writing on the social media site, a representative of the Cupertino based firm asked: 'How are you closing the App?' Hey, could be worse: It's not as bad as the macOS High Sierra flaw that allowed anyone to get administrative access to virtually any user account just by clicking unlock a bunch of times. Given the iOS 11.2 Beta had already demonstrated it wasn't impacted by the December 2 bug, Apple apparently took the decision to pull the trigger on its release earlier than we were expecting.
If you're affected by this issue, the best fix appears to be disabling notifications from any apps that use the local settings (turning all notifications off also works).
The iOS bug is the second big software blunder from Apple this week. The hallmark feature for US users is Apple Pay for iMessage, but that service reportedly won't go live until at least Monday. Here's what you need to know.
Besides the bug fix, iOS 11.2 includes the aforementioned Apple Pay for iMessage for US users, new wallpaper options for iPhone X users, and a handful of other minor improvements.
If that's too vague for iPhone users to understand, look for workout apps, medication reminder and similar apps that require local/scheduled notifications. Well, you will be more surprised after updating to iOS 11.2 as it will offer new features to your device.
