Hi,
This happened to me twice. When I checked my elevation plot during hiking activity I got the flat line. The first photo is the pre-loaded course elevation plot before hiking activity which is normal. The 2nd photo is the elevation plot I checked during my ~13k hiking activity. You can see the flat line display in the elevation plot. I got even longer flat line during the rest of hiking activity. After hiking, I checked my activity elevation plot looks good. It looks I can not attach more photos in this thread for reference. Is there anyone has this problem? I have 12.20 software installed in my watch.
Daniel
