I'm experiencing an issue trying to send course to device, each time I do, there's a load of previous failures listed along with 'segment-leaders' and I get the message "there was an error syncing with Garmin Connect". I've found the tread telling me how to navigate to Garmin/Express/RegisterdDevices/DeviceID/PendingSyncDownloads, there are a load of files in there which I trash.I've cleared all course off the device. When I go into connect to resend one that was previously successful, I get the sync error from GE again listing the same failed courses (not the one I just tried to upload) and the segment-leader files. If I navigate back to PendingSyncDownloads the files have all reappeared. I've restarted GE, restarted the mac, removed the device, added it again but nothing I do stops these old failures reappearing. The course that previously worked is not in the error list but is not on the device either.
Many thanks in advance for any help.
