For the Mojang team, I haven't been able to play Multiplayer on Local ever since you could saddle a Happy Ghast. I have spoken to Nintendo, Xbox, and Microsoft and they all say it's on your end. I have created three tickets… the other two were closed with no results as they were stumped. These screenshots of the issue and my step-by-step actions should give you an idea if it helps. This was also posted in the Minecraft Discord group and no one understands how I am still having this issue, but at least I can see that I'm not the only one.
