I've tried to join my friends' worlds countless amount of times and I've tried to make them join mine but it won't let me, so I tried to exit and re-enter the game and I made my friends do the same and it didn't work, so then I tried to un-install and re-install the game multiple times still nothing, and even when i completely deleted my in game data it still wouldn't let me play multiplayer though i can join servers without a problem which is a bit strange in my opinion since it is much easier to join a LAN game than to join a server
