I have a fēnix® 5S. My altimeter seems to track my elevation, but when I record an activity it no longer records my elevation during the activity.
On 20th Dec it recorded my elevation during a cycle to the swimming pool. It recorded my swim, and then it stopped recording my elevation during the cycle on the way home.
I have tried, soft reset, auto-calibrating and have updated to the latest software.
I am a regular swimmer. The only change to my activity on 20th Dec is that I started to swim a few lengths of crawl rather than only breaststroke.
Has anyone else experienced this and have you been able to resolve it?
