When trying to enter a specific world, a message pops up (There was a problem loading the world) and when you click on accept, it doesn't let you enter other worlds.
Another bug I have detected is that when loading a world and entering with split screen, after a few days, the second player will restart, losing everything in the inventory. When investigating what was happening I found that when entering any world and clicking on profile from the menu, another message pops up saying that I was not connected to Microsoft. I don't know if this has anything to do with it but I'm including it anyway.
