Starting June 01, I received "sync failed server error" message on Garmin Connect. Sleep, activities and heart data would not show up. Today I spent a half hour ton the phone with Garmin support. Evidently, there is a bug in the Yoga activity in the May 31 Garmin Connect update and they are aware of this and working on a fix. After we removed the yoga .fit file in the watch (via Explorer in Windows) and re synced, everything was working again.I would like to add that the lady at Garmin support (her name was Dallas) was super helpful. Just wanted to get this information out there since I could not find anything related to this on the forum.
