Steps to re-produce the issue/error:

• The msg is visible when you are in a local World
• When you press the "start" button on the xbox one s controller, you get the "Resume Game, Settings, Achievements, How to Play, Save & Quit" menu, and on the right hand side of the screen it says "Current World", and a message below it : "Oops! You were disconnected from Xbox Live To invite more players, reopen your world."

In addition to this is that on the first screen (Worlds/Friends/Servers):

• On the Worlds tab it says "We could not connect to Realms right now. We will try again soon",

• On the Servers Tab I can see 3 Servers, and when I try to connect to the first 2 servers (InPvP or Mineplex) the following message appears "Xbox Live Profile Required", then it disconnects and is back at the same screen where you select a server (or use the LB/RB to choose Worlds/Friends). If you try again to connect to the same server you get a different msg: "Disconnected from Server", and if you try again you get this message:"You Must be logged into XBL!"
• If I choose the 3rd server "Lifeboat Network", then it connects and we play against other players online in this world!!!!
  -Yet then when I then go to one of my own worlds (yes its set as multiplayer game), and you press the "start" button on the Xbox one s controller, on the right hand side of the screen it says "Current World", and a message below it : "Oops! You were disconnected from Xbox Live To invite more players, reopen your world." (When i'm not disconnected from Xbox live)
