Ski activity is not showing speed or distance. Last winter it did. All I get is vertical decent.

Ye mine is this same. Its rubbish doesn't work at all. Skitrax app on my phone is a million times better

This is what Connect and my watch are getting this year.

This is what was being recorded last year.

I used to get distance, speed, max speed and a resort map. Now those are all gone. They are not on the connect ap on the phone or on the watch either.

You need to set your activities as public, otherwise we cannot access them. 

I just changed them to public. Let me know if you can't see them

No i still can't access them 

I didn't realizze there was a separate step to all access to past activities. I had just updated new ones. They should all show up now. 

That looks like your GPS is not working. Did you start any other outdoor activity lately and if yes, are they looking okay?

I have not done anything since this summer when hiking was working fine. I did some GPS walks in the fall that were fine. I will try a walk this weekend and see if the GPS works for that.

I suppose the descent is based on the altimeter.

Yes, decent comes from the altimeter. Also check if GPS is activated in your activity settings
