I've discovered a problem with loading players from Game Center ids.
[GKPlayer loadPlayersForIdentifiers:@[@"G:111111111"] withCompletionHandler:^(NSArray *players, NSError *error)
{
Error Domain=GKErrorDomain Code=8 "The requested operation could not be completed because the player is invalid." UserInfo=0x156cc810 {GKServerStatusCode=5005, NSUnderlyingError=0x156c8a60 "The operation couldn’t be completed. status = 5005, NO SUCH PLAYER ID", NSLocalizedDescription=The requested operation could not be completed because the player is invalid.}
}];
The other player is not my Game Center friend and i retrieve his ID from connecting in an auto-match. Why can't i load the player from his ID ?
