Altimeter problem after upgrade to 15.20 firmware

After updating the firmware to version 15.20 I have with my Garmin fenix 5x plus similar problems with altimeter as described HERE. Has anyone noticed a similar problem or I am alone?

Thx

let me highlight that in this case any tests make sense only if you avoid the calibrations listed in points 1-3.
- Continuous Mode - During activities, the watch uses DEM mapping data, and GPS elevation…

Go to www8.garmin.com/.../download_details.jsp download the file. Unzip it and copy the gupdate.gcd file that you find in the System_Backdate_v14.00 folder.
Connect your device to the computer and paste gupdate.gcd inside the GARMIN folder of the watch .. it is impossible that there is not

I guess I misunderstood you, I was looking for the directory in the watches, not in the downloaded file. I downloaded the file and I already have it. Thank you.

Today I went to work 25 km, the real altitude profile of the route is 270m - 190m - 387m. The altimeter in the watch shows the following:

I used a car for the trip, not SpaceX :-).

I tried walking activity around 8 km in the afternoon, the altitude profile in the activity seems to be normal. I do not understand.

Firmware 22.20 for Fenix 5, where an altimeter and barometer problem has been reported, has also disappeared - https://www8.garmin.com/support/download_details.jsp?id=11435

It looks interesting...

I have exactly similar experience after 15.20. After car trip, massive fluctuations in altitude and air pressure. During activities no problems.

Just wanted to add my elevation issues with 15.20 with Fenix 5 Plus: Elevations during activities seem to be OK but when not in an activity I am getting random wild spikes and dips in elevations. Never had this problem before 15.20. The average elevation where I am is 350 feet or so. No mountains or deep sea dives!

Quite certain I didn't go diving during the last few hours, stationary at elevation 0 meters. I'll report it.

I upgraded the watch to software beta15.30 in my 5X Plus yesterday and confirmed that the problems with the altimeter and barometer have disappeared . It even seems to me that the accuracy of the altitude measurement has increased compared to the software 14.00.
