I own a garmin 410. Recently upgraded to express connect from the original ant uploader. Now half the time when the watch syncs, it goes through the motions but nothing is uploaded to garmin connect. It's very annoying to lose workouts. Anyone else experience this? Definitely not making me like my garmin watch anymore.
this is not a solution but report of a new problem connecting with the new interface.
I own a 410 watch as well. I have resorted successfully to the "OLD" interface. That worked for a time but upgrading the local software app to garmin express doesn't work quite the same and now it is not loading anything. I have not been able to upload anything to "modern" successfully.
What happens for me 1. open garmin express, click the "sync" button 2. my device and ANT are working properly and data is transferred (garmin express even tells me so) 3. open up Garmin Connect and there is no device recognized. (its like it doesn't recognize the app running on my computer - a macbook pro with the latest OSX) even clicking on the "VIEW DATA IN GARMIN CONNECT" doesn't show any of the latest activities.
