Crossplay 1.20 not working

Hello 

When we try crossplay from my Pc (windows 11) to a minecraft in switch everything is ok, second switch ok but when an extra player logs in via pc version of bedrock all the nintendo switch members from that (LAN) world are kicked out and cannot re enter untill that extra pc logs out. 

So mc 1.20 on pc via lan connects with 2nintendo switches 

but cannot connect with 2 nintendos AND a second pc.

Before update this worked.

 

Sorry for the bad explanation but i'm not sure how to explain better
