Edge Explore 2 does not record total ascent and total descent

My Explore 2 does record both ascent/descent values, visible in Garmin Connect (Web). While biking do you see the correct height values in a datafield that you have setup? You may check if the two small holes at the backside are not blocked by dirt / water or a badly fitting case. Being not very popular because you have to re-enter your personal data and settings, you could perform a soft reset or even a full reset to factory settings.

If everything negative contact your seller or Garmin.

Thanks for the reply, yes the altitude varies during the ascent and descent, while the total values ​​of ascent and descent always remain at 0
I tried to do an update and it seems to have started working again. Let's hope so

A software update in fact incorporates a full reset to factory defaults, so maybe a reset alone could also have solved the problem too. But good to hear you have good figures now, so fingers crossed it keeps working.
