No banner notifications in new iPhone X
Yesterday, I swapped out my iPhone 7 for a new iPhone X. I successfully restored the device and everything appears to be working fine, except I am not getting banner notifications for all my applications. Even for those that still show notifications, I do not see them unless I pull down the screen from the top left corner. I especially use an application called Pushover, and although new events can be pulled up in the app, there are no notifications when they arrive. I have uninstalled/reinstalled the app, I have soft reset the phone, I have disabled/re-enabled notifications for the app, and have even reset my network settings as noted on some forums, but still nothing. Does anyone have any ideas on how I can get notifications for all my apps going again? This is more than a little frustrating!
