First: Sometimes my Fitbit app says my cardio fitness score (31-35) says poor to fair, and sometimes it says fair even though the numbers haven’t changed. How can 31-35 be poor to fair some days and fair another??
Second: When I track my runs with my Versa 2 the GPS map says there isn’t enough heart rate data to display. I had this issue with my inspire HR but I thought it would have been fixed with the better model.
