When I send an invite to my friends to join my world it says they are unable to. When I try and join there's it says the same thing but they have no trouble joining other people except me. I've tried to uninstall the app, checked my setting on the app and the xbox privacy setting to what it's suppose to be and even made a new account but nothing works. What do I need to do to be able to play with my friends on minecraft?

The pictures are my settings for the game and Xbox privacy. When my friends join it says "unable to join world".
