I got an xbox for christmas. Today, I keep seeing that some of my microsoft account friends are on Minecraft. I try to join them but it says they're not in a world. One of my Nintendo Switch friends was one of the friends of mine on Minecraft so I started up the game on my switch to see that it said my friend was in a world but it says they were not signed into their microsoft account. This doesn't make sense because if they weren't signed into it, my xbox wouldn't say they are currently playing the game.
