Currently most, if not all, realms are showing only 1/3 & 1/4 M+ leaderboard data. Please identify and resolve this issue.
Original:
The Mythic+ Leaderboard seems to stop working as of 12/27 around 8:30 pm but RaiderIO is reporting the data. Please resolve this issue. It seems to be broken within the API.
Thanks
