I’m trying to join my friends world on Bedrock edition. It doesn’t let me. I have checked internet connection, our Xbox friendship, NAT type, have joined my own worlds and other multiplayer worlds including his other worlds, but still not able to join this world.
We apologize for the inconvenience, but this is currently a known issue. The team is currently working on a fix that we hope to have out to everyone as soon as possible. Thank you for your patience while we work on the solution!
