Friends can't join Minecraft Nintendo Switch worlds, and the games freezes for 5 seconds

Well, the game on Nintendo Switch is having a lot of bugs (from version 1.11.1, but I say this now as I thought it would be fixed in this recent version), I'll start with this one, and that is that, if you create a multiplayer game on Minecraft Nintendo Switch, nobody can join your world, if you import the platform (even Nintendo Switch), making it impossible to play with friends in my worlds, it really is very annoying.

And here goes the second annoying error, the game freezes for at least 5 seconds almost all the time, making, for example, a mob I killed myself because I can not react, even there are times when the game is closed because it just does not react, please solve this and pay attention to this message, thank you.
