Two days into tracking data on the iPhone 6, with MyFitnessPal integration, all steps data and other data has disappeared from the HealthKit dashboard, including the diet data from MyFitnessPal. Clicking Me hangs the app currently. Has anyone experienced this? It reduces confidence in this as an essential component of the iPhone experience. OS version: 8.0.2 Edit: An iPhone Reset fixed the issue, so apparently it's some sort of stability issue, not a bug per se.
