I created a course in Android Garmin Connect, and
- Pressed the send to device button
- Hit the star on the route
- Hit the general sync button in Connect Android
- Did both Bluetooth and Wifi sync (initiated from the watch)
The course did not sync.
Its the only course one called "Berlin...."
I've had MANY sync issues with workouts before, but assumed it was because they were created in Final Surge.
I have now got solid evidence of the Garmin-only infrastructure having issues.
Garmin-Sierra whatnl further information would be needed to raise an issue with the developers? Feel free to contact me via email.
Cheers!
