Spiders:

Playing Java Edition i’ve realise spiders on Bedrock does not make their Jumping-attack properly. The jumps are not synchronized at the time spiders try to hurt you, also not even try coming close to you by jumping considering a close range to the player as should be, or does not work at all; it’s like they just make their jumps randomly “as possible”  XD. On Java Edition they are way more dangerous, and their "jumping-attack"mechanic makes more sense. 

Another small issue about Spiders: 

Also, some cases they just forgets you if we try to get away after a while (keeping their range detection). we have to hit them another time, or just waiting a couple seconds until they detect us AGAIN.

Evidence: the 2 issues covered by one video.

Related to wolves:

The Only one issue is about the jumping-attack, which simply does not exist for wolves. They just follows us and make their ‘turn-animation’ on the floor (which should execute while jumping), but the jump never happens.

My video shows all these things off, and i do really hope get the developers fixing this because the PvE gets worse, keeping in mind the actual Survival Minecraft as easy as learning how to play with a ball, after playing it a couple months…Furthermore, this is not a parity issue, this behaviors were implemented along many versions ago, but since 3 or 4 versions these mechanics failed.
