Hi there, my name is Gerardo, and I'm an Xbox player. I'll be happy to assist you with any questions or concerns you may have.
When you purchase Robux directly from the Microsoft Store or Xbox Store, you do not receive a code as you would with the Microsoft Rewards program. Instead, the Robux purchase is automatically linked to your account.
If you do not have an Xbox console, please limit yourself to purchasing Robux directly within the game on the platform you are using to avoid issues. Robux bought from the Xbox Store will only be reflected in the game on an Xbox console, as indicated by the game's description and the "Playable on" section of the item.
Please keep in mind that in this public forum, we are just fellow players like you, trying to help other players with our best intentions.
I appreciate your understanding and if you have further questions please let me know.
Kind regards,
Gerardo.
