VO2 max- Apple Watch not showing as data source

Hi, I recently purchased a series 7. I updated all software on my iPhone and watch, have checked all privacy settings, location settings etc. Everything seems to be set correctly, however, when I access the cardio fitness or VO2 max section in my health app, it shows there is no data source and I cannot manually add my watch for this. I tried unpairing and repairing my watch, but this still persists. I understand I may need to log a few runs before it starts pushing the readings through, but I don’t understand why the health app isn’t even recognizing my watch as a data source? I did run for about 40 minutes yesterday as well, if that helps. Any advice or direction as to how to correct this beyond what’s already posted here would be of great help. Thanks in advance. I’m just trying to avoid running for a couple weeks and still having the issue persist if this is a sign it’s still not actually setup properly and then finding out after the fact.
