Apple Watch no longer syncing and reporting Cardio Fitness or Cardio Recovery since January / February 2025

Health App is no longer showing / reporting Cardio Fitness or Cardio Recovery since January / February 2025... I have followed every suggested fix with the exception of nuking all my health data.

I have a Series 8 watch and its on 11.3.1 (22S560) and my phone is 18.3.2

It beggars belief that Apple has not made a re-sync or any other kind of process that checks and updates all connections to it's own health app. Maybe it was the same team who worked on Photos, IOS Calculator etc ...

If anyone has a solve that doesn't involve jumping over a broomstick at the local park for 20 minutes that would be grand.

Given the watches inability to tell if I'm seated or standing in it's stats I guess I shouldn't be surprised.

Maybe they should get a product manager from Garmin...
