I am using the Forerunner 235 with the Android app. The watch is connected via bluetooth with the phone. I can tap "sync" in the app or on the watch, but the process finishes very quickly. In the app it still says "Last Sync 6/16/17" (today is 6/17), and the most recent data I see are from yesterday, 7:12pm. I tried power cycling the watch, but that had no effect. I did an activity for a few hours today, and I don't see that either.
I checked "Device Sync Audit" in the Settings, and it shows "Upload Status=SUCCESSFUL (No items to process)". That's obviously not true.
Thank for your help!!!
