My health app used to count my steps, flights climbed, walking distance. It hasn't since i got my 7 plus. When I try to make it start monitoring I go to the Health Data -> Activity ->Flights Climbed-> Data Sources. My iPhone is the only source. If I tap that I get the data up to the end of January listed. If I tap on the Source icon I get Apps - None, Devices - My iPhone. That will just lead to old data. How do I make this start recording again?
