As of recently everytime my friend invites me to their world it won't let me join, and when I try to invite them ti my world it also won't let me join, when I try to accept the invite it loads for a little and then pops up with a dirt screen with the words "Unable to join world" on the screen, and it does the same to them to, earlier on in the day I could play with another friend but it won't let me play with anyone anymore. We tried to restart our phones sign in and out of Microsoft and update our phones and nothing helped, I contacted an expert and they sent me here.
