After updated to the latest version of Garmin Connect Mobile (3.16.1.0), my watch (Vivoactive HR) has never been successfully synced with my phone. The app shows it is syncing but it will be failed at last.
My Phone: Nokia Lumia 930
Windows Version: Windows Mobile 10.0.15063.2
Watch: Vivoactive HR (Ver. 3.50)
Thanks for your support.
