In short, you cannot run roblox advertisements on paid access games.
Go in and create and ad. and no paid access games will be available to select from.
Expected behavior
I expect to be able to advertise paid access games like any other type of game.
Yeah it won’t likely perform well. but how else am I supposed to get new users?
This is intentional given the ad system is based on visits.
Essentially this would be a free money glitch because you could bid so that you’d make more money from the game purchase than the money you spent for the ad.
