Okay, so I've been waiting for days now and have yet to receive any update that allows me to play the 18 or so Xbox 360 games that I have from the initial release-list on my Xbox One. My console tells me there is no update available, a hard-reset didn't force any update, there's no "Xbox 360" app available to download, AND I'm in the preview program. All of the advertising I've seen says that it's available for preview members now and that digitally-owned titles will automatically be added to my list of games, but I don't have any of it! Is it rolling out over time? 'Cause I haven't heard anything of the sort. What I do know is that I've seen some friends already playing their Xbox 360 games such as Mass Effect, while I'm just sitting here completely out of the loop - and I HATE it.
So, where the heck is it!?
