I can't tell exactly how much of it is "stuck", but the top spots (weekly) for "すき points" definitely shouldn't be at ~10. Pretty sure it usually updates multiple times throughout the day. I'm guessing it hasn't updates at all since the initial weekly refresh.
Not a high-priority bug or anything, but I figured I'd point it out
Could possibly be related, but my "number of correct answers" leaderboard never updated last week; all the numbers stayed the same as they were the first day of the week.
Should be working better! Let me know if you still see something that seems off. (I only checked the すき points, but there was something blocking everything (rank-wise) from fully completing.
