I just filled out a bunch of recipients on the Revenue tab in a group, then realized I was on the Recurring Payout tab rather than One-time Payout tab. On switching tabs, I found that the list of recipients was wiped again and I had to re-enter the recipients.
As a developer I want to quickly pay out users and maintain my list of recipients if I realize I selected the wrong payment method.
If Roblox can address this concern, it would remove a point of frustration while paying out users.
