Black screen after opening the app with remote notification
Did you try to navigate to some undefined controllers in this event:
public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler)
If you haven't applied UserNotifications the event above will be called when you click the notification to open your application.
If you comment out that code will this black screen show up?
Maybe this issue was caused by the code of how you created the specific view controller.
