Hi, I'm developing a game under the iDUP ( iOS Developer University Program ) and I'm trying to use some of the functionalities of the GameCenter.Sadly every time I try to use the GC functionalities I got the message in the title, I also tried to add the game to the GC but AppStoreConnect doesn't let me do that ( the tab "MyApps" doesn't even exist in my dashboard ).Now I'm asking if there's someone else who can do this operation for me or simply I can't because of the program in which I'm enrolled.Does exist maybe another way to test the GC functionalities without adding my app to the Game Center?Thank you.
