  1. click purchase product/gamepss in game, and then cancel
    repeat 1 many times, client log print this picture bug.
    and then i can’t purchase anything in game, i must leave game and enter again.

we enter many other games ,repeat step1, show the same question.
we test this problem in studio, but never print this bug.
anyone know how to solve it?

maybe in game purchase, it’s caused by checking player robux is sufficient to purchase this item?

Hi Ada, thanks for the report! We are taking a look.

Would you mind telling us a little bit more about what platform you are seeing this on (e.g Android, IOS, Windows)? Are you attempting to purchase a product that cost more to your balance? Also, can you provide an example of a specific product in the game where this is occurring?

1.on windows.
2.My balance is 0，so anytime i attempting to purchase, keep getting this problem.
3.my game:[🦑UPD] Fish Training🦈 - Roblox
not a specific product, any product in shop,
The point is Frequently click on any product, then cancel , next other product, then cancel… maybe repeat 10~20 times
