Apple has released iOS 10.1.1. It says, "This update fixes bugs including an issue where Health data could not be viewed for some users."

Does anyone find the Health app to be useful. I've tried using it with my Garmin vivosmart HR watch and all I get is garbage. It does not seem to give me accurate information. The Garmin Connect app gives me a lot of useful information, but the Health app is a total fail. It connects to my vivosmart HR okay, but it just doesn't work well with it. Perhaps it works better with the Apple Watch.
