    Hello,

    When executing AddPlayerScoreAsync via Task.Run, Unity throws an exception:

    Code (CSharp):
    1. Task.Run(async () => { await LeaderboardsService.Instance.AddPlayerScoreAsync(leaderboardID, score); });
    "UnityEngine.UnityException: get_unscaledTime can only be called from the main thread."

    Originating from

    Code (CSharp):
    1. public bool RateLimited => Time.unscaledTime < m_rateLimitUntilUnscaledTime;
    As a result, the submission is silently swallowed and never occurs.

    [EDIT]
    Just noticed you can happily just call async methods in Unity, as long as you don't need the return immediately (which I don't). So that works perfectly fine. Sorry for the confusion!

    Thanks,
    Chris

    Hi Chris,

    Great job! Just to provide a bit more information, the exception is actually intentional. Web requests must be made from the main thread, which is why this exception occurs.

    Thank you,
    Neal
