I have got Fenix 5 plus, and is heavy user of it, its predcessors, and vivosmart models.
Device syncs fine with GCM, or either via WiFi. All daily stats and activities appear after sync.
The problem is with Training Status. It is seen on the watch and in Garmin Connect web-based portal, but GCM always shows "No status". Even removing and re-installing application, and re-pairing device did not help.
Any suggestions?
