this is seriously getting me mad no more custom challenges, no classified section on the website, no more watchlist, no xbox live marketplace items in the halo waypoint store, no videos,can’t view milestones and awards,no more halo 4 interactive guide, no more watching/redeeming forward unto dawn
The classifieds section can still be accessed using the xbox 360 app, which I believe also has awards and milestones. Most of the videos have moved over to the Halo Channel and you can manage your queue here.
