Since the update to 10.43 this last week I face serious issues with the altitude tracking of actrivities.
Yesterday I did a Mountainbike ride which was 470m planned I the Fenix recorded 730m.
Moreover today I did a long 4k walk at the beach.
As you can imagine there is not much ascent and descent when walking along the beach but Fenix recorded 45m ascent and 70m descent.
I also switched the altimeter calibration from Auto into During Night and calibrated manually at the beach.
Same issue.
Never had such an issue before the firmware update to 10.43.
Any ideas?
