Hi everyone! I'm experiencing an issue about Game Center's authentication behaviour. Login prompt is now displayed immediately if user is not logged in to Game Center on System Settings / Game Center. Expected behaviour (Before 14.5 beta 5): Set callback to authenticateHandler at app launch. Callback fired: If viewController is null, this means user logged in to Game Center and we successfully authenticated user. User sees a Game Center banner says "Signed in as nickname" If viewController is not null, this means user not logged in to Game Center in settings. If you want to show user a login prompt, use viewController. If you don't want to show user a login prompt, end authentication flow and user won't see a login prompt. Current behaviour (After 14.5 beta 5): Set callback to authenticateHandler at app launch. iOS immediately shows login prompt if user not logged in to Game Center, before callback fired. Does anyone encounter same issue? I don't want to show login prompt to users if they are not logged into Game Center. My solution was working fine until 14.5 beta 5. Any help will be appreciated.
