As a relative newbie, I managed to create a course on Garmin Express and send it to the device....no problem. That was a week ago.
Today, I tried creating a course from a ride I did today
* if I try from the 810 itself (create course from ride), the course shows on the 810 but when hitting Sync in Garmin Express it says "Sync complete", but the course never shows up in Garmin Connect,
* if I try from Garmin Connect (go to the Activity itself and press the little gear icon and select Save As course), the course is show in Garmin Connect, but when hitting Sync in Garmin Express it says Sync Complete, but the course does not show on the 810
Basically courses are not being synced either way :(
Am I missing something here ? I have tried creating a new 0.5 mile course on GC (which is what I did a week ago)....that does not show up either.
The only thing that has changed is I have updated the device from 3.20 to 3.40, and updated Garmin Express to the latest version (3.2.27.0)
