I start off by saying. 
I don't care is this reported before.
I care that it is not fixed since... The bow was first time coded to the game.

There's lag associated with players turning while shooting arrows.

Turn 180 decrees and shoot the arrow.
Arrow goes 90 decrees to the wrong direction.
Even thought You with 100% sertanty + video evidence did let go of the arrow at the right time instead of that 90 decrees wrong direction.

Because of stuff like this, Java players no come to Bedrock.
