Starting Dec 2, 2020, Fenix continuously showing abnormal heart rate alerts. Usually I get this alert after workout or an intensive task. However, I was totally fine on 2nd and I felt uneasy and fatigue starting Dec 3. Tested positive for COVID-19 with CT value of 34. I stopped wearing the watch while I am hospital. After starting of an experimental anti-viral drug, I started feeling normal and my body battery started coming back to normal.
Thank you, Garmin! You saved my life!!
