VO2 max not recording

My watch was automatically recording my VO2 max, then it stopped. It has not recorded a VO2 max for the last two months. I have checked all apps and settings. I have restarted my phone and watch. Anyone have suggestions how to restore this function?

VO2 max needs your body measurements, like height and weight, to make its estimate.. Have these disappeared from data in your Health app?


Apple says, "t can take at least 24 hours of wearing your Apple Watch, followed by several workouts* and passive measurements with your Apple Watch before you receive an initial estimate."

FYI: my VO2 graph includes a point for each day I exercise. Not random dates. Does your activity app record all your walks and runs?
