If you visit the configure place page and navigate to the access tab, you will see very quickly that it says the fee is 90% with a minimum amount of 1 robux. Attempt to enter any less than 25 however and you’ll get a popup saying it’s too low.
It’s not really of any major concern, but something that could do with being changed.
Also a separate bug I noticed upon checking this is that if you have a paid access game, you can’t disable the place for mobile and tablet. This is an issue since a game may be in beta and not developed for mobile devices so you don’t want to give them access on a mobile device.
