I see a Fitness Age and VO2 max on Garmin connect but not my Fenix 7.

Me neither see fitness age on my Enduro 2. It is “- -“. But no problem with VO2max.

VO2 changes everywhere for me. Fitness age, on the other hand, has stayed the same on the watch for two years, in app/desktop it continuously changes.

Don't you see your VO2 Max when you open your "Training Status" or "Performance" widget?

Don't you see the Fitness age under settings > User Profile?

I do see VO2 max, and it is changing aftter each of my run with Enduro 2, the chart shows it.

But as you write I dont see F.A. in user profile.

Btw  an active discussion had already started here in Epix 2 forum https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/epix-2/286321/fitness-age/1850343#1850343 before I got the first reaction here appr half an hour ago.

I will post there from now on to avoid double posting.

Is it a recent watch? Fitness age will use your training intensity, resting heart rate and BMI. Maybe it needs more history or data on your watch?

Yep, exactly 2 weeks old.

And you have a valid bet. Although GC knows everything about me it seems that changing my Primary Training Devive and P. Wearable does not include the transmission of the full knowledge pack to the new device.

OK. Give it a few weeks and then reassess. These algorithms are specific to the watch and run on the watch. Only results are synched back for graphing. For example, you will have a history of VO2 Max data points, but the calculations and detailed data during/from the runs are only on the watch.

Logical. Btw in Recommendations section of Fitness Age page there are more items are expressed as 4w avg.
