GameCenter Leaderboard Reporting Scores

Right, so this is driving me insane. I have implemented a GameCenter leaderboard in my game to view high scores. GameCenter authentication works and I can view the leaderboard, but no scores are showing up despite having reported a score.

My main code for the leaderboard:

     public class SocialPlatformController : MonoBehaviour {
 
     public static SocialPlatformController controller;
     private static string LEADERBOARD_ID = "MyHighScoreLeaderboard";
     public bool m_loginSuccessful;
 
     void Awake()
     {
         if (controller == null)
         {
             DontDestroyOnLoad(gameObject);
             controller = this;
         }
         else if (controller != this)
         {
             Destroy(gameObject);
         }
     }
 
     // Use this for initialization
     void Start () {
         Social.localUser.Authenticate(ProcessAuthentication);
     }
 
     public void ProcessAuthentication (bool success) {
         if (success) {
             Debug.Log("Authenticated user.");
         }
         else
         {
             Debug.Log("Failed to authenticate user.");
         }
         m_loginSuccessful = success;
     }
 
     public void DisplayLeaderboard() {
         //Social.ShowLeaderboardUI();
         GameCenterPlatform.ShowLeaderboardUI(LEADERBOARD_ID, TimeScope.AllTime);
     }
 
     public void SetHighScore(int score) {
         long highScore = (long)score;
         if (m_loginSuccessful)
         {
             Social.ReportScore(highScore, LEADERBOARD_ID, success =>
             {
                 Debug.Log(success ? "Reported score successfully." : "Failed to report score.");
             });
         }
         else 
         {
             Social.localUser.Authenticate(ProcessAuthentication);
             if (m_loginSuccessful)
             {
                 Social.ReportScore(highScore, LEADERBOARD_ID, success =>
                 {
                     Debug.Log(success ? "Reported score successfully." : "Failed to report score.");
                 });
             }
         }
     }
 }

When I report a score, I do something like this:

 //Yes, my score has to be an object for various reasons
 object highScore = 50.015f;
 //Convert the object into an int, to simplify the score
 int convertedHighScore = (int)(float)highScore;
 //Report the score
 SocialPlatformController.controller.SetHighScore(convertedHighScore);

The leaderboard is live and attached to my app, which also just went live. Please help!
