I think this started with 22.18 (or maybe the version before), but all of a sudden elevation gain is way off, like ~300m instead of ~60m.
Never had any issues before.

Had similar issue. Elevation was off most of the time. Activities with the same start/end would have over 200 meters difference between ascent and descent and even activities on flat courses would show…
Elevation has been ALWAYS off since I have FR955 from day 1.
It's because altimeter is influenced from temperature. Here it's winter and when I start a run the altimeter immedeately jumps 50m above actual…
A quick comparison. On the top a run during summer, on the bottom a run in winter. Same roads, it's a round-track I use for 90% of my trainings, you can see between red lines a single "lap" of 2250m.…
This is actually getting silly. Here is what it looks like:
But this is what it should look like:
Clearly it's a complete mess at the moment.
Thank goodness for Strava's "Correct Elevation" feature!
Updated to 22.21 and today is warm so temperature shouldn't be an issue and yet still I am getting:
instead of:
This is a 5x1200m training on a linear track with nearly no elevation gain/loss "in real life".
Done calibration just few seconds before start, real starting quote was 110m, but the watch immedeately registered 140m since first second. Why?!
Done a 1200m to south, then recover steady for 1min, then 1200m to north, steady for 1min and so on.
2 things are funny:
1) as usual, quote is increasing when watch temperature is decreasing (start the run with 1° outside)
2) during each rest, no moving, quote is decreasing by about 4m!
This is the behaviour of my watch since day 1 in november 2023
Did you have really 0 elevation or something around?
There is a known bug which might cause you get really 0 elevation for an activity. But this is IMHO the only bug.
All other issues seem to be hardware related. (But it is better to let the users think it might be software so you do not get that much replacement requests 
)
According to what I have observed here in the forum, there are 3 types of devices:
Type one - works great withing about 1% deviation
Type two - has some drift (at the acclimatisation periode) but works then within an acceptable range
Type three - displays clearly wrong values
AdrianI would try to get a replacement.
One side note to the elevation correction with the map model - this works if you are in a pretty flat terrain but if you are in a hilly area or in the mountains 2m off with your position might cause several meters elevation. Thus you need a lot of filtering (which you can see, looking at those smooth curves). So I made the experience that the elevation change calculated based on the map model in nearly all cases underestimates the real eleveation change.
