Health app borked
iPhone 6, iOS 8.3. I had just started using the Health app to track two data points, my weight and my blood glucose. I had also set the "emergency card" data. I started this a couple weeks ago, my plan is to enter data weekly to get an overall trend rather than obsess about it daily.
Today, I went to add data, and the app had completely reset itself to defaults. The default dashboard items were back, mine were gone, the "emergency card" was not set up, and my dashboard items had no data. Further to this, after putting my dashboard items back and trying to add today's data, it's not taking it. I enter the new data, tap "add" and the only thing that happens is that the data entry screen goes away, the data is not added.
The only change I'm aware of is a manual device reboot. There was no restore and no crashes I'm aware of.
