Hi,

We're using GameSparks for Unity, and we want to automatically use device authentication once GameSparks fires the available delegate, and then the user can decide to log in to facebook to migrate the player. 

We were noticing that the userId returned when connecting first with device authentication is different when later connecting with facebook. Is this intended behaviour? Posting a score while authenticated by device and posting a score while authenticated by facebook creates two different entries (even if the score is the same).

So the questions are:

1) If merging has been properly done, would the same playerId be used?

2) Are we doing something wrong the in code (below)?

public class BackendManager : MonoBehaviour
{
	string[] READ_PERMISSIONS = { "user_friends", "email" };

	void Start()
	{
		FB.Init(OnFacebookInitialised);
		GS.GameSparksAvailable = OnGameSparksAvailable;
	}

	void OnGameSparksAvailable(bool isAvailable)
	{
		if (isAvailable &&
		    !FB.IsLoggedIn)
		{
			new DeviceAuthenticationRequest().Send((response) =>
				{
				if (response.HasErrors)
				{
					Debug.LogError("Error connecting to gamesparks anonymously " + response.Errors.ToString());
				} else
				{
					Debug.Log("Connected anonymously with user Id " + response.UserId);
				}
				});
		}
	}

	void OnFacebookInitialised()
	{
		Debug.Log("Facebook Initialised. Logged in? " + FB.IsLoggedIn);
	}

	void OnFacebookLogin(ILoginResult result)
	{
		if (result.Error != null)
		{
			Debug.LogError("Error logging in to facebook: " + result.Error);
		} else
		{
			new FacebookConnectRequest().SetAccessToken(AccessToken.CurrentAccessToken.TokenString).
				SetDoNotLinkToCurrentPlayer(false).
				SetSwitchIfPossible(true).
				Send((response) =>
				{
				if (response.HasErrors)
				{
					Debug.LogError("Something failed with connecting with Facebook: " + response.Errors.ToString());
				}
				else
				{
					Debug.Log("Connected with Facebook successfully " + response.UserId);
				}
				});
		}
	}

	public void OnLoginToFacebookButtonClickMsg()
	{
		FB.LogInWithReadPermissions(READ_PERMISSIONS, OnFacebookLogin);
	}
}
