Watch series 4 stopped recording VO2max after OS7 upgrade

My watch stopped recording Vo2 max data after I upgraded my phone and watch to latest OS ie ios14.0.1 and watchos 7.0.1. Earlier, I was facing excess battery drain after upgrading which I was able to fix by unpairing the watch and setting it up again as new watch. Now its working fine except this anamoly that it stopped recording vo2max.

See If you're missing Workout GPS routes or Health data after updating to iOS 14 and watchOS 7

This should correct most issues


For the VO2 Max, I had to reset my Fitness Calibration Data and then do 2 workouts.

It is now working again.
