Hey Dan, big fan of your work.
I seem to be having the same issue and this doesn't seem to be resolving the issue. I have it written like this; am I not calling the method inside the callback properly?
Thanks a lot.
LeaderboardCreator.UploadNewEntry(publicLeaderBoardKey, username, score, ((msg) => {
LeaderboardCreator.ResetPlayer();
GetLeaderboard();
}));
