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!
