I have also been having issues with steps myself. I have a 9PP, and I was walking on my desk treadmill even walking for 2 hours at 1.0 (which should be 2 miles) I got 700 steps.
While I definitely think the improvements to not be as sensitive to every wrist flick is great, I think the scaling went a little too far where it will track accurately if I’m actually using gps or doing a jog and really moving my arms/motion.
