Seemed like every time I looked at the watch it was just trying to update heart rate data, so it was super slow at updating my current heart rate or didn’t show it at all.

My series 2 is super accurate and always shows my heart rate when I look at it while running. Could be the watch moved more with the new nylon loop, I’m hoping that’s it and not the watch or new os4. I actually thought it was tighter than the old sports band, next time I’m using my old band to seeing differences.

Anyone else not seeing any heart rate readings when running or very slow to update heart rate?
