Hi

Currently unable to join an online world and play splitscreen. 

First player can join a world and play normally. Once the second player tries to join, it goes through all the loading screens and then the message pops up saying "disconnected from server".

Still able to play splitscreen local world on the Switch and host other players.

Nintendo online accounts for both players and a family membership/subscription.

This is a more recent issues as it used to work flawlessly playing splitscreen online.

Feel like I have an account setting that is wrong or something. 

Thanks for your help and suggestions

p.s. already hard booted, restarted an power cycled in to see of that would help as boot times for Minecraft have been unbearable long. Reducing the amount of world's created on the local Switch has helped with booting, still pretty slow.
