When I try to join the world from my friend's screen, the connection fails and times out. The conditions for success and failure are unknown, but the first time you connect the world to the internet that day, you are more likely to succeed in multiplayer. Request a patch now. Or rather, if you have time to change the wallpaper one by one, fix this long-standing bug! Every time I update and fix a bug, the number of bugs increases again! Please do something about it!
