If you go Garmin Connect web , profile and account on your thumbnail / Account settings/ User Settings you can manually update it
My vo2 max shows 32 for a long time. My fitness age is 73. I'm 46 years old, I exercise every day, I did the tests, including stress tests and ekg. Doctors says I'm fine, garmin says I'm going to die soon…
Tried that, for my cycling value. This has had no effect on the values in the reports, web site or watch. User setting has the value I want, all other reported values are unchanged, does not ever change…
Off course, I tried everything
Could you share a link to an activity that you believe should give a higher VO₂max value than 32? Perhaps we can spot where the problem comes from.

I have trained swimming heavily with it and have not been able to obtain a single VO2 max measurement.
No Garmin watch calculates VO₂max for swimming. Only running, walking, and cycling (but you need a powermeter for that). No swimming.
I imported a .fit file that unknowingly contained power meter data in it. Now my cycling VO2Max is messed up. I deleted the activity with the mistaken data, but the effect on my VO2Max will not change. In fact, when you go back through the history of VO2Max, the datapoint shows up on the graph, but there is no apparent way to delete it. How do you get rid of a problem like this? Updating my profile vo2max does nothing. Come on Garmin, what's the point of tracking data if we can't fix errors like this?
