I just got about 4 hours and 45 mins worth of double xp. I entered it and applied it to my gamer tag like I have always done and I got nothing. Is anyone else having a problem with double xp codes right now??
You have to be signed in to your account, go to the multiplayer menu, apply your double xp, once it says the xp has been applied, go to the dashboard on your xbox, and then start back up MW3. Enjoy your double xp. :thumbup:
