I also have the same issue. I want to play multiplayer with a friend and I can see that he is playing on the “friends” tab, but I cannot join. We even tried inviting each other and accepting the invites. It just keeps saying “Unable to connect to world”. We have the same version (v1.16.201) and even tried restarting the app and devices. I even went to the extent of trying it other devices (ex. iPad, iPhone, Android) and still ended up with the same thing.
