iPhone 6 health data is gone
I got my iPhone 6 on launch day and it was immediately tracking steps, flights climbed and total mileage. Today, after 6 PM all that data disappeared and the health app dashboard was empty. I can't seem to get my data back even after I've re-added those three items to the dashboard. If I go to show all data, it just tells me there is no data. I have rebooted the device, but everything is still blank.
I can't seem to find anything online where this was working and then it stopped, nor data cleared out.
Any help or suggestions would be appreciated.
iPhone 6, iOS 8
