Puls reading low after update to 21.19

bpm is to low during activity. maybe 20-30 bpm to low.

Done two workouts now and hade same issue (Strength workout). First time it "fixes" itself after 20-30min but I had to remove and re-attach the watch 4-5 times.

I now get down to 80 BPM in rest between sets (I rest 1 min) and before i never got down under 110-120bpm.

I could do more anecdote but something is wrong or the old firmware was wrong as it's a clear differance. 

  • Known issue. Started ocurring often after some updates during 2024. Many people complained (the same issue affects range of zgarmin watches) but Garmin does not care at all and ignored the issue completely.

  • I do think is is seperate from that. As my watch worked fine before the update. But if there is no big influx of complaints it may not be a general issue. 

    It may be due to my specific settings that trigger it. 

  • Did a bike ride today. Got an avg. 130 bpm. That is bottom of Z2 for me. I would expect 144-148 avg. 

    it looks like it’s low bpm that inaccurate. When I do a hill and it “feels” like I’m at 165 bpm the watch shows basically spot on 165 +\-2.
