Hi, I'm trying to sync my Edge 520 with Garmin Express but receive the message 'Some files could not be sent to your device. segment-leaders (Transfer Error)'. I currently use Strava Live Segments but had the same error when I switched back to Garmin Segments.
I've reinstalled the Edge software and Garmin Express. I've manually deleted sync upload files from the computer.
Ride data does seem to sync from the device to GE but I can't see any segments on the device.
I should add that I've also tried disconnecting and reconnecting my Strava Premium account with Garmin Connect.
Any help much appreciated!
