Sudden drop in VO2Max recorded on Apple Watch

I had a sudden drop in my VO2Max, as calculated by my Apple Watch 3, of 10 points, overnight! Picked up this question thread from early 2020 when similar occurred to others, but this has now gone silent. Have all those who flagged the issue found a permanent fix? If so can you share this please? Thanks

Had my Series 6 for one week. My readings have gone from 39 to 32 to 30 to 31 to amazingly today to 21.

Yes I’m 68 years old but 41-39 has been my reading on my last watch for 3 years. AM I DYING or is there a major problem?????
