I also see jitter on PC. The underlying cause is that Time.deltaTime varies greatly (from 2ms to 30ms for me) even with VSync enabled and a 60Hz monitor refresh rate.

Is your bug with the Rigidbody Interpolator, or is the underlying cause Time.deltaTime variation which the Rigidbody Interpolator internally uses?

It appears that the issue is either less noticeable or perhaps non-existent on an iPhoneX with Unity 2017.3.0(f3). I have only tested with one level and will add another comment if I am mistaken.
