What is the Reason to Cause iOS 15/14/13/12 Never-ending Notification to Update

The pop-up message is caused by a data calculation bug in iOS 12 beta 11, which thinks its expiration date is nearby and therefore keeps prompting users to upgrade to the newest software.

“It looks like this method in Springboard does some date/time calculations to determine if the current build is about to expire, every time the cover sheet gets dismissed. For some reason, the latest builds of iOS 12 think they're about to expire. ” developer Guilherme Rambo said in tweet.
