First of all, I am Japanese and I am speaking through a translator. Please understand that there are some strange sentences here and there.

--------------------------------
I mainly play ONE JUMP of Minecraft parkour on the PE version of MCBE (MCPE)

The problem I want to report is the misalignment of viewpoints executed by command

But this problem is only in Mobaiban and there seems to be no problem in PC.

And please refer to the video to see what the problem is.
For example, let's say you have a gimmick that avoids walls. x.5859 y0.0 z.5859 f.20.5859
The problem is that when you execute the command tp here, f (viewpoint) is shifted.

And this misalignment is a big problem: on the PC, you can avoid the wall, but on the PE, this misalignment causes you to hit the wall.

This is not a problem for us, of course we have not touched the screen.

P.S.
For example, with this gimmick
W+D run1tick→W+D+JUMP→W+D+ JUMP→W+D+ JUMP→W+D+ run1tick→W+JUMP(1tick)→W+A
But MCPE can only do W+D run1tick→W+D+JUMP→W+D+ JUMP due to the shift in viewpoint, which means that run1t is not possible, or even if Code is modified, the run1t may hit the wall.
