@MojangSupport You seem to be having some serious lag and disconnect issues with your cross play feature at the moment. Playing on an Xbox one and a Nintendo switch both in the same house and still getting connection issues and frequent disconnects.

When did you start noticing this and are you noticing this on any other networks, if you've been able to try? Is this constant for you or intermittent? -JL

Seems like the problem was having the Switch being the one hosting. Things tended to be more stable when the Xbox One was the host.
