After migrating my iOS leaderboard to a group and adding to this group my macOS game, I can't get to display my leaderboards anywhere.
After testing in real devices, I don't get errors when reporting scores to the leaderbords with the grp prefix, but when trying to display the gamecenter leaderbords I only get the "No Data Availble", also when trying to force load the scores on my leaderboards using the GKLeaderboard() .loadscores I get the following error: "The requested operation could not be completed due to an error communicating with the server."
