Since MCPE 1.16.200 Multiplayer on LAN just does not work.

It is really frustrating because I’ve tried everything to solve it and nothing seems to work. This is obviously a problem with MCPE itself. I tried to join a friends’ LAN world and it “connects to server” for 30 seconds and tells me that it was unable to connect. LAN is the only reason I still play minecraft. Please fix.
