I'm using an iPhone 5 (running iOS 8.3) and update my health data manually with 'add data' feature. However in some mornings when I open health application, all data seems missing. Charts, dashboard settings, everything. Like I opened for the first time. If I reset or restart my phone, data comes back.
Has anyone experienced this? If yes, is there a solution to keep it from happening?
Update: I didn't restart my phone intentionally and my dashboard is still empty.
Update 2: Issue is not happening for some time now. May close the question with some answer soon.
Update 3: Still present with iOS 9.0.1 upto some extent. I'm starting to think it's a bug and slowly being ironed out.
Update 4: Still happens with iOS 9.1, however less frequently. Let's wait and see what iOS 9.2 brings.
