We need to fix this ASAP @MojangSupport bugs.mojang.com/browse/MCPE-…

I can understand how that can feel frustrating. Maybe we can take a look into your case and see if we try some troubleshooting steps. The issue is on (I take it this meant 1.20.20) of Bedrock Edition, do I have that right? Just so I understand, what's happening on your end? -AG

Since the beta/preview 1.20.20.20 my fps mark dropped down and affects mostly entity, opening the inventory and loading chunks( this last one is the most; whenever I turn my camera view and load some chunks the screen freeze for a couple of seconds.

Don't know if this is useful, but that was the same beta when you adjusted the amount of particles from the cherry leaves based of the device performance and I live in a Cherry Grove, so... I don't know.
