Multiplayer issues on Xbox app and in the game.

 Multiplayer Issues - I cant join my friends worlds because when i try to enter it always says, Unable to connect the world, and i can't see invites anymore. I had dowloaded the xbox app to play with they and before all this, all was ok and not full of bugs, i dont know what happened, i even checked my privacy settings. Not much to say...if i find more bugs ill update i think.
