Custom Games/ Loading bar won't fill at all/ Stuck

Nothing I do works… Ive turned my Xbox One off, and back on… Ive exited the game and relaunched it… Ive uninstalled and reinstalled… But I keep getting stuck on loading screens in custom games, and I can’t play with anyone. Even ALONE in a custom game :frowning:

Also, No adjusting game audio? Sound effects/ Music?.. :frowning:

AND… When I play co-op on campaign… between my game and my friends we get off sync, he’ll be telling me I’m falling off the level/ commiting suicide when on my screen he/she is! :frowning: PLEASE HELPP
