I want to add a couple game passes to my game but game passes that aren't mine show up instead. So I link my game pass and all but then when I try to test it it's something I've never seen before like a shirt for 2 robux. Tried it on a new template with nothing on it and the same issue occurs, what the hell is happening?
Use MarketplaceService:PromptGamePassPurchase instead of MarketplaceService:PromptPurchase. The former is meant for game passes, while the latter is meant for assets.
