I'm using my Vivoactive 4 "cross country skiing" activity while skiing and I have noticed that HR hardly goes over 100 BPM, even real HR is between 130 - 160 BPM (verified with another watch). I have tried to adjust watch position on my wrist etc, but HR-levels are still same. Walking or running activities are working fine and those are giving proper hear rate information.
Does any one else facing similar issues in cross country skiing activity? Garmin support, help!?
