As a Roblox player it is currently too easy to accidentally purchase something while playing Xbox. This is because the same button to activate a GUI or jump is used to confirm a purchase.
When playing with some friends yesterday night, I accidentally bought a developer product in a game because I tried to jump at the same time I accidentally triggered the prompt. This is undesirable and hurts my experience as a player. The purchase button should either be turned off until the prompt is fully loaded and open, or there should be an additional action needed to complete a purchase.
I also encountered a game last night that prompted me to purchase a very expensive developer product whenever I went to go jump, which was very scummy but would have worked had I had that amount of Robux on my account. I reported the game after experiencing that, but I fear it might be an easy way to scam users. Changing the behavior of the purchase prompt would help solve this issue as well.
