Hi, my Garmin Forerunner 245 is not able to sync any of my health stats (heart rate, stress, body battery, etc.) after repeatedly synchronising. My steps were synchronised. After rebooting (just turning on and off) my stats were still on my watch but my app started after rebooting. Why am I not able to sync all of the data and do I get only the data from after the reboot? My watch is just 3 weeks old...
