Minecraft version 1.19.21 is now available on Nintendo Switch and players should once again be able to join others through cross-platform multiplayer. Thanks for your patience while we worked to resolve the issue. -MG

Switch is having problems still with invalid sessions. If marketplace is not accessible they will not load into the game with current progress, instead will start at spawn. PS4 is having problems with uploading a world onto realm. I can join realm. Can’t upload world to realm.
