Apple Watch 5 not displaying VO2 Max in Health App

Every time I ran or walked using the Watch Workout app, I was getting regular V02 Max readings from my Apple Watch 5 display in my Health app. Over the past week, I have run 3 times, and Health app is not displaying updated VO2 max readings. The last one was on May 20, 2021, and today is May 29, 2021 (see screen shots). I have been through the settings, and everything appears to be set correctly. I do recall that there has been a Watch update in the last week. Might that have affected it? Any other guidance is appreciated.

Thank you!
