I want to confirm Alexander D's loss of mobs bug.

I have this happened to my small sheep farm, about 12 to 15 sheep before the update, but afterwards there were only 2 left over.
I did not mention this in my comment in the other so called 'resolved' thread because I thought lightning might have struck them because it rained the last time I played before the update. 
Even though I couldn't recall any lightning struck nearby, I still went with it anyway.
So yes, it's definitely a bug.

Another bug that I have experienced is with tamed wolves.

When I make them sit, instead of just sitting and facing the direction that they were supposed to be facing, they would turn their whole body around to face whichever direction that you're at even though they're sitting.
They basically try to track where you are. This results in them sometimes glitching out: they would track you and glitch back to their original direction and glitch back to your direction over and over.
The wolves glitching only occur sometimes but they will always try face your direction while sitting.

I made an account just to vote this issue.
I was really hyped for the update to hit but once I finally got the update, my existing world lags and the game crashes upon save&quitting my world. I haven't been able to play minecraft on the switch because of this.

Also want to mention that the game lags in both hanheld and docked mode. Even if I don't travel at all and just stay in the same area, after about 5 min the game WILL start lagging even though it ran just fine earlier.
