Shared leaderboard for free and paid version of app?
Hi all! I currently have a free app that has been available on the app store for about a year now, and I would like to create a paid version of this app which grants all features and unlockables to the user. The problem I am faced with is that the free version of the app already has around 400 users on the leaderboards, and I would like for the free-to-play users and pay-to-play users to be able to compete with each other over a shared leaderboard. Would it somehow be possible to link the 2 leaderboards between the 2 apps, or have the 2 apps reference the same leaderboard so that all users may compete with one another? Thanks in advance!

canStartWithMinimumPlayers AutoMatching Behaviour
Is canStartWithMinimumPlayers(false) ignored when auto-matching opponents? Without sending invites, setting the desired opponent number to 3, with a minimum of 2. canStartWithMinimumPlayers is set to false. All devices are on iOS 15. Press Start, auto-matching begins. 2 players connect and the game begins without waiting for the third. From the example video, after two friends have accepted invites, the host is allowed to start at minimum and auto-matching continues in the background. What is the expected behaviour of canStartWithMinimumPlayers when auto-matching?

Game Center login issues
With the recent update to the iPhone, they required me to login again to my account for Game Center. Unfortunately, I have not had to do it for so long that I don’t remember my password. When I went to retrieve a new password, I realized my account is attached to an old email that is now defunct. How can I fix this problem?

App does not support achievement
I have an app in development that uses GameKit to show leaderboards and achievements. All seem to work well until I added Achievements. Now not only does the new achievements not show up, I am unable to also add any new leaderboards to the app. (Error Domain=GKErrorDomain Code=3 "The requested operation could not be completed due to an error communicating with the server." UserInfo={GKServerStatusCode=5044, NSLocalizedDescription=The requested operation could not be completed due to an error communicating with the server., NSUnderlyingError=0x283ee3510 {Error Domain=GKServerErrorDomain Code=5044 "status = 5044, App does not support achievements" UserInfo={GKServerStatusCode=5044, NSLocalizedFailureReason=status = 5044, App does not support achievements}}}) This is what I am seeing on my console when I do  GKAchievement.loadAchievements { (achievements, error) in                          if error != nil {                 print("Error \(error)")             } else {                 print("\(achievements)")             }         } I have tried everything including adding a new leaderboard, removing, reordering etc.. What am I missing here ?

Game Center won’t load and will show an error
When I go into the Game Center tab in settings it would show the error “The operation couldn’t be completed”. I don’t know how this happened or how to fix it. I had this problem before but I just left it alone and it worked again. (Sorry for the wrong tag I’m new to using this)

How do I handle accepted multiplayer invites with Fast Start?
Hi, I'm trying to implement the following Fast Start code shown during WWDC 2021 . However, I'm getting an error on the GameSceneViewController line. I've tried this with both a Game and an App template in Xcode 13, but both get hung up here. Can anyone help me make this work? Thank you so much
