Exactly the same problem as some have described above on the Switch - it keeps disconnecting from the Microsoft account, and I have to use sign in link for Microsoft, but get kicked out of the Microsoft account almost immediately. Last attempt took 13 times before it "stuck" but it kicked out again later in the day. My son is too young to do this on his own and it's very frustrating that he can't play Minecraft with his friends.
