Multiplayer

I’m on mcpe version 1.10.0. My problem is that when I’m out of a game or world, I can access the game and edit it and see that multiplayer is on. Unfortunately, when I’m in game I see that multiplayer is turned off and I can’t turn it on because it is greyed off. I try to exit the game and once again it says it’s on on the world settings. When I get back into the game it says it’s off! Please help.
