Is the feature to request leaderboard moderation through the support hub not working for anyone else? It says "You cannot submit a moderation request because you must have email authentication turned on and your account must be at least 1 month old. To turn on email authentication, visit your account Settings." even though I do have email authentication enabled, and my account is older than 1 month. Am I missing something, or is it just bugged for me?

Someone had the same bug. You need to go to your user settings, and "save" them again (without changing anything).
This should correctly register the email authentication setting.

@Oreo321Oreo321 That worked for me, thank you!
