When I have my world open on my windows 11 computer, it has no issues leaving the roof open and available to play for other people such as my brother and best friend to play on my world, but we will play for a couple minutes, they’ll leave on their iPhone/ iPad. And they will come back and the world isn’t available to join anymore, even after reopening the application, and restarting their device. It has happened more than once, and even after restarting the computer, restarting the Minecraft application on my computer, it stills perceives to give this issue pretty often, and it’s definitely a bug that needs worked on
