To summarize, me and a friend and his other friends wanted to play Minecraft together. So our plan was to have me host the world on my PC (Windows 11) then have my other friend play on their switch and join my world, then the other friends would join split screen. When we did it, my friend could join but when the other friends tried to join, they would load into the loading screen, and then it would instantly boot them out. I tried many different debugging attempts but we could not find out what was causing the issue so I’m thinking it’s a bug.
I have been seeing a similar symptom on and off for about the last two months.
Scenario:
Nintendo Switch
Nintendo Online account for main user (parent)
Both kids are in the Nintendo Online account as a family
Microsoft Realms subscription for the main user (parent)
Both kids also registered in the Xbox Family account with MS accounts
When playing in Online mode in either
A friend’s world on their PC
A REALMS world
the same happens: second player can join, loading screen, screen gets split, then second player immediately gets booted and returns to non-split screen.
This has been intermittent with worlds hosted on PC, but pretty consistently non-functional in REALMS over the last week.
Note that the problem doesn’t seem occur when joining a friend’s world on their Switch.
