Switch Switch multiplayer problem

[ForeverPyrite🌳]

The lost connections do seem to sometimes occur during a host auto-save, although I cannot say with certainty that it always occurs during a host auto-save.

and

we have this same problem
One switch can join friends world no problem other one can not
But the one that can not join friends world can join when I host
Can’t figure out why the second switch can’t join other friends world at all

Usually, one, or all switches will disconnect either at the beginning of a boss battle (especially with moon lord), or as soon as the boss is changing phases. I don't know if it is because the game is broadcasting a signal that is also somehow disconnecting players or what.
