I have the exact same problem except I can't even join other people's games. The issue is only for p2p worlds, realms works just fine. The enable "Multiplayer Game" Toggle is greyed out in the world settings along with related settings. Attempting to join a friend's world results in the message "Unable to connect to world". The problem is account wide, it happens on both my phone and PC. Reinstalling the game on both platforms did nothing to help. Not sure what else to do. I should also add that I have confirmed all my Xbox One/Windows 10 Privacy settings are correct, and those are not the problem.
