I got the iPhone 6 the day it was released. I immediately started using the new Health app. I added the basics, birthday, age, sex, weight, and I added the "Steps" and "Walking + Running Distance" to the dashbaord. I notice they automatically started tracking my steps. So I went for a jog, it tracked that also. Awesome, so far so good. But the next day it was all gone. It doesn't matter if I select "Day / Week / Month / Year" at the top top, the stats are always the same, they only show the current day. I've checked each day since I've got the phone, each day it seems to start over. Why is all the previous data disappearing? Thanks!
