I've had my fitbit Versa for over 2 years now and yesterday evening/night it started measuring my heart rate as if I was doing fat burn/cardio. This continued as I slept with many "intense workouts" being tracked throughout tonight. As I've been sitting today it's been doing the same thing. I've trying turning my fitbit versa on and off but that hasn't helped at all. I've also compared to charge 3 and the versa is reading double sometimes triple what my heart rate actually is.
