[Hand Tracking] FingerTipPokeTool Index does not follow my index

Hello everyone.
I created a simple scene with some hand tracking and added a "Interactable Tool Creator".
It creates some finger tip poke so I can interact with buttons but the tip does not follow my index finger tips.
Here is a video recorded on the Oculus Quest and a screenshot of my project scene.

On solution seems to go to Edit>Project Setting>Time  and change Fixed Timestep to 0.005 and Maximum Allowed Timestep  to 0.05.

as described here : https://forums.oculusvr.com/developer/discussion/86423/hand-physics-capsules-not-following-the-fingers#latest

But this seems dangerous. Also why when Fixed Timestep is to 0.05 it does not work AT ALL (I mean, not 10x slower as we could expected) ?

I'm still getting this.  In FingerTipPokeTool.cs I see the following suspicious comment:
// NOTE: use time settings 0.0111111/0.02 to make collisions work correctly!

I fixed this issue by adding 2 lines here:

OVRSkeleton.cs
private void FixedUpdate()
...
if (capsuleGO.activeSelf)
{
capsuleGO.SetActive(false);                  //Added by Raymond Tsang
capsuleGO.SetActive(true);                  //Added by Raymond Tsang
capsule.CapsuleRigidbody.MovePosition(bone.position);
capsule.CapsuleRigidbody.MoveRotation(bone.rotation);
}

Apparently, if you edit oculus integtations code, hands will stop rendering on build, but will work with quest link. And even if you get the script back to a previous state or delete the whole Oculus folder and reimport new plugin again - it still won't render. The only solution I found is to make a new project and reimport all the assets. So I would not edit their scripts. I wasted 3 days looking for a solution. Thanks facebook dev team for ever mentioning that hand tracking will loose access if someone tries to fix your code

Update: ok, very cool. My life is a joke. The cause was different. Hand tracking won't load if you disable unity splash screen :)))) Why did I choose this career path. I will file a bug report if there's any energy left in me to spend on this

 This worked perfectly for me! Thank you so much!!

And Btw this issue [this thread's] is still there even now, when Hand Tracking v2 is out and the quickfix works
