As far as I can tell there's no way to view which users are sharing revenue with you. The user that's sharing can see who they're sharing with, but the receiving user can only view notifications when an actual sale is done and they get money from it.

This is a problem cause potentially there's nothing stopping the seller from removing that revenue share to take the full % from a few sales and then enabling it again. A way to view your current shared revenue, or at least a notification when you're added/removed from a revenue share, would be appreciated.

edit: From the comments, turns out this feature already exists but it's a bit hidden away. It should simply be moved to the merchant home menus
