Bought a Versa 3 a year ago, mainly to track pulse during bike rides, but that's the one thing its worst at. I start a 45-minute ride with a decent charge, clean underside of watch and clean wrist, wear it snug, but not too tight, just how its recommended but it rarely tracks my heart rate right during a 45 minute ride. Sleep tracking is a joke.
