VO2 Max never updates on my Fenix 6X

I have a Garmin Fenix 6X and I've read every guide there is on how to correctly register a VO2 max activity.

I exercise five times a week but mostly long hikes with heavy backpack. I know this doesn't meet the criteria for measuring VO2 max so I occasionally go for a run activity in hope of updating my VO2 max value on my device.

But it never updates and I can't understand what the problem is?

* I have a chest strap heart rate monitor

* I run for more than 15 minutes

* I have a constant heart rate above 70% for more than 10 min

* I use the activity Run in my device

* I have GPS activated

What also bothers me is that my VO2 max value is stuck at 38 in my profile and every time I open Garmin Connect on my phone I get this status that I'm "Poor" shoved in my face and I refuse to believe it's correct.

Any ideas?

mine update. 6 pro. if i cycle too long on zone 2, after a couple of weeks, my vo2 goes down. if i re introduce harder and longer workout, it will go back up.

OP doesn't ask how to move the vo2max in any direction - the question is why it doesn't record any value !
Not sure why some always answer on this kind of questions with how to do vo2max training.

My reading of the OP is different. I understood the OP statement:

To mean that the displayed VO2 Max value of 38 doesn't change - i.e. the displayed value of 38 is stuck on 38.

If that reading is correct, then it is appropriate to define the actions required to register a new VO2 Max result.
