I created a Minecraft world for me and my friend, but he hasn’t been able to join lately. No matter what we try or what we do, it still says “Unable To Connect To World”. We can join the same server just fine, like Life Boat or Cube Craft, but he still can’t join my world. We’re on the same iOS version, same WiFi, everything. We tried logging out of our accounts with no success, as well as close the app several times and shut our phones completely off. Please advise what else we can do. Thank you.
