Health app
The Health app appears to have been broken by the latest iOS update. It is now recording phantom flights of stairs climbed. It has been generally accurate in the past. But in the past few days, it has been wildly inaccurate, showing 25 flights climbed Friday when the actual number should have been four, and today recording 18 flights climbed, rather than a correct total of 4. Some of this “stair climbing” took place while I was walking or on a bus. Other folks from a different Mac forum are reporting the same problem.
iPhone 6, iOS 10.3.1
