Is it possible to change the Cover Art in the Xbox Dashboard?

Hi, I'm Luis a Xbox user just like you. Thanks for reaching out us here. Unfortunately there is no way change the art cover when ordering a game

1st of all Aegis Wing is a U.S. only game so the cover art will not be on the UK dashboard. Halo CE has never shown the cover art, even when I have played it. The other games not showing cover art, could be that the other games don't have their cover art
just yet. They is actually quite a few games that don't have their cover art (Sonic the Hedgehog 1 is one without cover art at the moment on the marketplace).

Greetings, Strat! We're aware of this issue and are currently investigating. I don't have any updates at this time -- sorry about that! Thanks in advance for your patience.

I tried clearing my cache and re-downloading my Xbox Live profile and that ultimately worked, so it might be worth a shot for anyone else still with this problem.

First, clear your cache:

support.xbox.com/.../clear-system-cache

Next, re-download your Xbox Live profile:

support.xbox.com/.../profile-move-delete

This did not fix the issue immediately for me, but upon playing Fez for 5 minutes and the game randomly resetting, I was pleasantly surprised to see the cover art is now present.

It should also be noted that when viewing my profile when logging on to xbox.com, there is no cover art shown for Fez (just a blank white box) whereas other games do show cover art.
