I have tried to play three different titles under the preview update for July- WatchDogs, Forza5, and Battlefield 4. None of them make it past their load screen and Forza won't even install properly (I just bought it). One other app that fails to work is Twitch. It freezes after I hit 'Broadcast'. None of these games or apps had any trouble before installing the latest preview. Is there a way to roll-back to a stable version? I can't do anything fun on my Xbox One right now.
