I have used the Push Notifications Console and verify that the test notification reaches my device (it says "not necessarily the app"). However, GameCenter notifications are not reaching the app. When one device passes the turn, the turn is successfully passed as seen in the Matchmaker VC. However, the app does not get the turn pass notification whether or not it is running. No banner appears if the app is not running (but it does when using the Push Notifications Console).
Please advise.
There sure area lot more questions posted than helpful replies in these forums. No response even by Apple. I submitted a request for help and they asked for screenshots! Of what? The lack of a banner notification?
Upshot of it all, if you're having this problem, move your app to Test Flight - that uses the production notification system, whereas Xcode and the simulator do not and are very low priority. After moving my app to Test Flight, I got all the notifications expected.
