On my Xbox 360, the Plex app at open, gives me an error stating "Service Not Avaialble" check Xbox live.com/status. Well, the Xbox status is fine.
I have deleted the app, cleared cache, reloaded the app, repeated the same steps after re doing initial setup, and the Plex app is still not working.
I have read on here, but there seems to be no true solution for my error.
It acts as if the App no longer is available to Xbox.
