Has anyone else started to see large gaps in wrist HR readings lately? This is occurring with me mostly during sleep. I’m seeing multiple gaps each night that range from a few minutes all the way up to an hour or so. I’m not sure but it seems this issue started occurring with the 4.20 software update. I know it has nothing to do with how I wear my watch because I exchanged my watch for a new one from the retailer I purchased it from and the issue still occurs.
i have had the same problem...Garmin seems unable or unwilling to fix this...I have reported the matter too. The upgrades have not addressed it...by the way..i am dark skinned and this seems to be part of the problem...i wonder how many other dark skinned 5x plus users have this problem..i did not have this issue with the 5x i upgraded from.
I started noticing that there are gaps in the optical HR readings during running. I checked, and these go back into July. In Garmin Connect, if I click on Heart Rate under My Day, I can see the gap and a number is shown as the High heart rate that is not consistent with what I would normally have during a run. If I click on the running activity itself under My Day, the correct heart rate is shown without any dropouts. I spoke to Garmin about this, and they suggested deleting and re-installing the Run app, If this does not work, they want me to return the watch.
