Assets/Tests/PlayModeTests/AppleSignInTests.cs(41,34): error CS7036: There is no argument given that corresponds to the required formal parameter 'onComplete' of 'LootLockerSDKManager.RefreshAppleSession(string, string, Action<LootLockerAppleSessionResponse>)' <- Tests need to be updated for this change
