Xbox cell gaming?

Does anybody know if you happen to’re Xbox HAS to be turned on for distant play? I’ve learn that it must be turned on initially so you may join your Xbox to the app, however then supposedly it doesn’t must be turned on after that. A man I’m pals with says he performs on his lunch break free from house with out the console being turned on nevertheless it simply received’t work for me. My Xbox is correctly linked to the app, however by no means will get previous the “can’t connect with your console proper now” bit. Thanks prematurely!!
