Cardio Fitness not working on my Apple Watch Series 6 (or on my previous Series 5)
I have owned an Apple Watch (first series 5 and now series 6) since November of 2019. I frequently run or walk outdoors for much more than 20 minutes at a time and I always use the Apple Watch Workout app, selecting either Outdoor Walk or Outdoor Run, accordingly. In 14 months of this outdoor activity (hundreds of runs and walks by now), I have only had Cardio Fitness data recorded ONCE (December 5th, 2019, and called VO2Max then). Before and since that random single entry, NO DATA has been recorded for VO2Max or Cardio Fitness. I compared the other workout parameters (exercise time, heart rate information, active calories) for that single workout that recorded a VO2Max entry with the data from my hundreds of other workouts but I don’t see any significant differences, other than the fact that VO2Max data was NOT RECORDED. When I traded my series 5 watch for a series 6 this past November 2020 I had hoped that this feature would start working, but nothing has changed (NO DATA for Cardio Fitness, aka VO2Max). I don’t normally take my phone with me with I exercise outdoors, but even when I do, NO DATA is recorded for this parameter. I have reset my Fitness Calibration Data several times in an effort to get this feature to work, but still NO DATA is ever recorded. What really has me confused is that it did work ONCE, but has not worked before or since that one day and I didn’t do anything different on that one day. Any ideas? Is this a know bug?
