VO2max not changing during training cycles since the new Edge 1040

Since changing from the 530 to the 1040 my VO2max shows 59 for 4 month without changes, independent of the training cycle I'm in. Previously it was fluctuating between 57 and 64. According to Garmin (data files provided) my VO2max varied between 59 and 59.4 and that the new 1040 measures differently. Anyone else has this experience. 59 as an average is about right but my VO2max can not be the same in my off season as well as in the final building block with tapering.

Edge 1040 primary training device

Vivoactive 4 primary wearable.

When I used my 1030 & 1030 plus, along with my garmin warch, the vo2 max used to change, but with the 1040 it does not. Seams this is a 1040 issue.

I have the same problem - Edge 1040 as primary training device and a Fenix 7 watch. My vo2max hasn't changed since December 2023.

Since this time I Head about 121 cycling activities with about 4000km.

It looks like it happened at some point when switching from version 19.19 to 19.21 or 19.22. one of many things that don't work with this device

So in the history of owning the 1040, this week I've have had my first ever increase in VO2 Max, only by 1 but it's a start! Software version 20.xx

Anyone else seen an increase on the 20.xx firware? My 1030 and 1030+ always gave increases, and decreases regularly, the 1040 nothing until this week

Apparently it happened on the 14.xx update from what I've read the VO2 Max not updating

Question to all, are you using the 1040 as the primary training device or your watch?

I don't know how much of a difference it makes but Garmin do recommend that where possible the PW & PTD should be the same device.
