Wrong HR rate with Garmin MARQ 2 (Athlete)

Do you have already see issues with HR rate with Garmin MARQ 2 (Athlete) ?

For instance on this screeshoot the HR is really to low: around 60 bpm and pace 8:20 /km.

Big drop on this second screnshot.

Hardware or software bugs ?

This is the same problem many, including myself, have reported with the Epix Gen 2 (and others) for the past year. It appears to have begun with one of the firmware updates. Garmin denies there's a problem. Good luck.

Did a run yesterday in the cold (-1°C) and heart rate (wrist based only) was immediately correct. Will test some more.

I’m not sure there is a link with temperature. If I remember with lower temperatures precision goes down.
