I have a iPad Pro 9.7", Apple TV, iPhone 7 and Apple Watch all on the latest software. I love the calories and heart rate being displayed on my iPad or Apple TV, but it has never worked through an entire workout. Then I spend 10 minutes trying to fix it which totally throws off the workout. More troubling than that is when I am done working out it gives false data sometimes saying no calories burned or zero minutes and other times showing 999 minutes. Does anyone have this working consistently?
