why can't I close my exercise ring on my new apple five watch.
I bought a new Apple Watch and I can't close my exercise ring. I just did a 1.7 mile walk outside to calibrate 31 min. and It gave me 13. Yesterday I walked 31 min. on treadmill and it gave me 1 min. What am I doing wrong? I have had series 2, 3, and 4 and never had this problem.
