Can't see my GameCenter Leaderboards

Hi,

I don't know if the problem is on the iTunes connect side or Unity.

I'm trying to use GameCenter for my iOS game, just for a simple leaderboard. I configured it on iTunes Connect already:

In the prepare-for-submission t$$anonymous$$ng, I also added my leaderboard to the game center t$$anonymous$$ng there..

now... I call

Social.localUser.Authenticate()

and I know it works, because I have a button in my GUI that opens the leaderboards via

 Social.ShowLeaderboardUI();

However, t$$anonymous$$s game center screen that opens always shows "no Data available", even though I submitted scores using

 Social.ReportScore(scoreLong, "sessionKills", LeaderBoardCallback);

my callback function does:

 function LeaderBoardCallback(result:boolean)
 {
      if(result==true)
      {
          Debug.Log("score submission successful, according to the API");
      }
      else
      {
          Debug.Log("score submission failed");
      }
 }

and In the Xcode console,. when the game is running on my iPhone, I can see "score submission successful, according to the API", so It seems like I submitted scores. But I can't tell! The leaderboards don't show. Am I missing somet$$anonymous$$ng?
