I have a Fenix 5 Plus running the latests 10.0 software and I went skiing yesterday. To my surprise, when I launched the app and pressed start, the app would not work at all. The first time it got stuck at 0:02:00 activity time and I thought I might have stoppped the tracker without knowing. But I tried again and this time the time didn't even move.
During the descent, the speed would not register, neither would the altitude.
It was about 250m high at the most.
I tried to reboot the device to no avail.
My friend's Vivoactive 3 would work no problem on the other hand.
Any help appreciated!
Thanks.
