Multiple Months Gifted with hiding Gift Privacy setting
In the Settings Page Under Security and Privacy there is a setting to "Hide Progressive Gifter Badge and Gifts Given Count" when enabled it hides the number of subs you have given as well as you name from showing up in the leaderboard. This works fine until you gift multiple months(note worthy the total subs given is hidden but not the leaderboard). I assume because gifting multiple months to a user counts as more than 1 sub it tracks you in the leaderboard in a separate way. I honestly am not sure if hiding the user in the leaderboard should be associated with this toggle or a different toggle but obviously the inconsistency between the two types of gift is a bug. I personally don't really mind it but it would be nice if this was resolved and additionally if these behaviors where separated into their own toggle. Good Luck and Excellent Job you have a great application <3
EDIT: These subs only show up temporarily I am not sure if this is just client side or not.
