A question we have get asked a few times is “How do I appear offline on XBOX ONE” . Are you trying to watch Netflix and do not want the annoying messages popping up then here is the solution :-
Before you login, go to Settings and Network, and go offline. Then log in to your profile, go to friends, my profile, show offline. Then go back to settings and Network, go online, then “connect to xbox live” on the main screen.
This will always keep you offline until you change this setting back.
