How to reduce positional desync with changing velocity (eg standing on a moving sine platform) ?

Players networked with TransformView that are standing on moving platforms that move with dampening (sin wave) always slide at the peaks of the movement on ALL TransformView settings (interpolate lerp, estimate speed, extrapolate speed, etc).

How can I resolve this?

Regular movement appears fine.
