When I'm trying to join my friend worlds a message appears saying "unable to connect to the world" (I have the language set in Spanish so it might not say the same in English ), and the same message appears to them when they are trying to connect my worlds. We all have multiplayer activated, and set to "only friends", we are already added on our XBOX accounts, we all have the same version, and they have iOS devices, we all have a stable Wi-Fi connection.
