I've struggled with this issue since the day I bought the Forerunner one year ago.
GC does not send training data to the watch. I've tried with the old Ant agent, and with the new Garmin Express, and still it doesn't work.
I've done a complete reset of the watch, and still it doesn't work.
I've ended up editing the training directly on the watch (terrible user experience).
Is there a known solution to this problem?
Can Garmin support provide help on this?
Thanks,
Andrea
