I have just synced my Garmin 610 with Garmin Connect for the first time in several months and there are multiple activities missing for no obvious reason. For example today's run and 30/12/16 and 24/12/16 runs were synced but not the run I did on 27/12/16. Also some cycle commutes have synced for one way of the commute but not the return journey. I have entered a 1000m challenge for 2017 and I obviously want to make sure all of my activity is recorded. I am not sure whether the issue is with my watch or Garmin Connect. Any ideas?
I am having the same issue. My run from Dec 31 2016 synced, but anything after the new year is not showing up in my calendar or linking to STRAVA. However, it shows in my history on the watch. It says "sync complete", yet nothing shows up. I have the Forerunner 920XT and my iPhone app is updated to the latest version.
