Amazon.com: Garmin vívofit 4 activity tracker with 1+ year battery life and color display. Large, Black. 010-01847-03 : Sports & Outdoors
Garmin connect stopped reporting my body battery ( vivo smart 4 ) 3 days ago. Since then it says "no available data". It has worked well for about a year. Any ideas? -
