I have a couple of problems with this release:

• Loading a world takes ages, If you accidentally hit home during loading, just forget it, the game will freeze and crash
• Performance is very bad, low fps all around. Bedrock used to be 60fps ish but on 1.9.0 it's barely a stable 30
• Save & Quit freezes the game quite often, resulting in me having to manually close the game, causing it to crash, losing all of my progress.

If additional information is needed I'm happy to help!

Good luck
