What is different on Bedrock that I wouldn't expect?

I've always seen differences between Java and Bedrock but as I've only played Java for near 15 years I don't know it all, the Wither is different, the combat mechanics, stuff like that I had heard about.

But what I never heard was that passive mobs work differently. They despawn unless I've bred/leashed/tamed them. Which although subtle really threw me off when I went to round up some animals I saw on my first night.

What other minor gameplay differences are likely to trip me up that I've never heard of?
