Installed dragons teeth but not letting me play it??

on your home screen go over to select the play disc (BF4) and push the button that has 3 bars on it (it is in same spot the xbox 360's start use to be) and select quit battlefield 4 and then try restarting it then it should work.

Otherwise the xbox one since it is set up to just resume game and most updates require a restart even on PC which is why if you have a 360 it tells you it must restart to install basically when it restarts it will run the new information otherwise it wont recognize it. Hope this helps! :D

haha ya i know basically it is never off unless you unplug it cause internet explorer keeps pulling up what i was at last other than a home page.

Glad I could help though!! :D

I have the same problem, but quitting BF4 didn't solve it for me ☹️
