How do I resolve this issue?

The game was purchased in the XBox Store from XBox online. This bundle included the game and many different downloadable car packs. In game, they appeared in my message center. When I try to accept the cars, it says my settings won't allow them to be downloaded.

I found a video last night detailing how to reset the XBox to factory settings, but I haven't tried it yet, but I'm hopeful that this will work.

I feel like I wasted money on this purchase, as I'm being denied what I paid for.

Try logging out of your account and logging back in to see if that fixes it. You can also try redeeming through other devices such as the Xbox mobile or desktop app. Try restarting the console as well.

I hope I helped and see you soon.

when you say it came with "a bunch of gift cards" where did you get this offer from? What specifically did it include?

Yes surely. The article below has information to help you about the Xbox mobile app.

I've tried logging out of my account and back in, exiting the game completely and going back in, resetting the console, full powering off of the consolez and even resetting the router. I've tried going online into my Microsoft account and adjusting the setting their, too. Nothing has seemed to work. I'm not familiar with using a mobile app. Could you give me more details?
