Too Many FlowState Stability Issues - Insta360 One R

I've had the Insta360 One R for less than 2 weeks now and I've shot nearly 100 clips. In the last few days of shooting I've noticed that the FlowState stability has gotten profressively worse. After shooting a couple of days ago, I recalibrated the gyros but that seemed to make it worse, as you will see on this video. The problem is nausiating when you look just under the horizon. The trail is also paved and pretty flat. This run is 3.6 miles, all down hill, so we were cruising at about 15-20 mph.

This is shot with the 4k mod, using the same handle bar bike mount I have used for all 4k mod videos. FlowState stabilty is enabled on the camera and also checked in Insta360 Studio 2020. HDR is not enabled, of course. Remove night time grain was also enabled during rendering.

Anyone have an ideas on what could be wrong and/or how to improve this?

I also tried rendering without Remove Night Time Grain enabled.. horrible:

Thank you!
