Part of the reason I bought the Apple Watch is so I could know what my heart rate is doing when I exercise. I did a couple of bike rides specifically to check this, and each time, the iPhone health app shows data coming in right up until I start riding, then there is a 2 hour gap in data (the time that I rode), then the data resumes. When I am not exercising, the heart rate monitor passes heart rate info to the Heath app on the iPhone every 5 minutes, but when I exercise, the info stops coming and doesn't resume until you stop exercising. Is anyone else seeing this problem? Is the a bug or did Apple do this intentionally? IF they did this intentionally, WTF?
