I got my 5 plus a couple of weeks ago. The first couple of runs were fine, but since then, I've seen crazy elevation charts. Runs that in actuality have ~300ft of gain are showing up in GC with 2k ft gain.
Here's an example run:
https://connect.garmin.com/modern/activity/2840836417
I've attached 2 elevation charts: one from GC, and the other from strava. Same activity, but I asked strava to correct the elevation based on GPS coordinates. GC says this was 2,047 ft of gain, whereas strava says 321 ft. I've done this run a bunch of times, and the corrected figure is accurate.
What appears to be happening is that the fenix 5 plus is going through weird oscillations where it's swinging +/- 50ft every couple of minutes.
I tried doing the calibration routine, but every time I attempt to calibrate (settings -> sensors -> altimeter -> calibrate), it just says "calibration failed."
I opened a support case with Garmin earlier this week, but crickets there.
Anyone else seeing this? ciq.forums.garmin.com/.../1375923.png ciq.forums.garmin.com/.../1375924.png
