Configuration: iPhone Xs Max, iOS 13.4 Reproducibility: 100% After using notification centre all applications stop receiving such lifecycle events as UIApplication.applicationDidBecomeActive(_:) and UIApplication.applicationWillResignActive(_:). Steps: 1 Launch any app with push notifications 2 while application is in foreground state receive a new push notification and expand it by swipe gesture 3 tap «More» 4 tap on «Settings» 5 navigate back to the application Expected: applicationDidBecomeActive would be called Actual: The only applicationWillEnterForeground is called Notes: Killing an app and opening again changes nothing. System-wide these lifecycle methods are not delivered to any application anymore. Only applicationWillEnterForeground and applicationDidEnterBackground work. To fix this required either to restart the device or to receive new push a tap «view» After that, all lifecycle methods are fixed and delivered. These lifecycle events are crucial to add/remove blur on switching between apps and protect users from exposing their private info
