Google Play Services leaderboard - player rank always 0

Hello,

I have an issue with the Google Play Services Leaderboard and I am stuck for days already.

I am using the Play Games Plugin for Unity https://github.com/playgameservices/play-games-plugin-for-unity.

I am trying to get the Userrank for a specific level. Therefore I am loading the Scores via the LoadScores Function and this seems to work fine.

The issue seems to be, that I get a correct rank in the "LoadScores" Function but the overall GetUserRank Function is still returning rank = 0, no matter what the actual Userrank is.

My guess is that this is a timing issue after all and that the rank is returned before the LoadScores Function has calculated the correct rank to return.

 public int GetUserRank(string levelID)
     {
         int rank = 0;
         string user = PlayGamesPlatform.Instance.localUser.id;
         string leaderboard = ReturnLeaderboard(levelID);
     Social.LoadScores(leaderboard, scores =>
     {
         if (scores.Length > 0)
         {
             Debug.Log("Retrieved " + scores.Length + " scores");
 
                 //Filter the score with the user name
                 for (int i = 0; i < scores.Length; i++)
             {
                 if (user == scores[i].userID)
                 {
                     rank = scores[i].rank;
                         // This prints out the actual rank of the user and seems to work
                         print("Rank in LoadScoresFunction: " + rank);
                     break;
                 }
             }
         }
         else
             Debug.Log("Failed to retrieved score");
     });
     //Here the rank is always 0, no matter the outcome of the LoadScores Function above
     print("Rank in PlayGamesController: " + rank);
     return rank;
 
     }

I reference this function from other scripts via:

 int rank = PlayGamesController.Instance.GetUserRank(levelID);

Any ideas/hints greatly appreciated.

Thanks!
