When trying to play split screen on my realm: The main player log ins fine but when the second player trys to log in. It allowa them to pick there account and the it goes to loading terrain and then just glitches. Then the second login shuts down. The main player still works fine and can continue to play. We have different logins and different combinations of logins.
Environment
Nintendo Switch. Updated to most recent versions.
Same issue. When second player tries to join, you get to select a player, then you see the second players loading progress screen appear (showing zero progress) then the split screen shuts down and only player one remains, which works as normal.
Throughout it all, player one continues to play as normal, just a second player cannot successfully join.
