Why is Apple Watch VO2 max trash?
My VO2 max on the Apple Watch used to be online with other calculations but since I got the six it is trash. It is not even close. Any ideas why?
Apple Watch Series 6, watchOS 7

You might need to setup VO2 max with your new iPhone and watch combination.
This information comes from:

Apple Watch may log your VO2 max, but you can’t currently check it on the watch itself. To see your stats, you must use the Health app on your iPhone. Go to Health Data > Activity and scroll down to find it. If you have readings for the current month, they will be highlighted in a big orange box. If you have no VO2 max data, it will be languishing at the bottom of the list, under No Recorded Data.
If you can’t find any VO2 max readings in the Health app, that is probably because you have not yet logged the right kind of workouts with your watch. Only two workout types can produce an estimated VO2 max on Apple Watch: Outdoor Walk and Outdoor Run. (However, I believe Hiking also works.)
VO2 max relates to maximal exertion. So you’ll need to log a pretty intensive workout to generate a reading. And you’ll need to sustain it for at least 20 minutes.
The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.
