I have a Forerunner 45S & have been following a Garmin Coach challenge for the past 3 weeks. Today, despite the challenge for today appearing on my iPhone, my watch does not show it. All other data is being synced ok, including "normal" runs, steps etc. But, when I try and sync my watch to pick up the Coach challenge the watch stats "sync failed". I have tried rebooting both devices. Any thoughts please?
