Series 9 - VOmax and Cardio Recovery

I upgraded from the Series 6 to 9 this weekend and it showed an immediate significant drop of VOmax and stopped giving me a cardio recovery reading. Am I missing something? Seems something is off.

VO2Max is not recording Throughout the years of extensive outdoor running activities, I have never faced such problem regarding VO2Max. The last calculated VO2Max was shown in September 1, 2022 and even though there’s lots of outdoor running sessions for over 20 Days, the Health Application doesn’t show the updated VO2Max. Is there anyone who’s facing this and what’s your suggestions to fix it. Thanks a lot.
