After July 22, 2019 update, the I watch with tracking activity. Even if I select an activity all it does is start the stopwatch - Doesn’t track distance or calories. Doesn’t track standing time, activity time, along with a chosen activity
Make sure your iPhone was updated as well. Next, reset your watch bt pressing in the crown and side button until you see the Apple logo, then release both.
After my watch took the latest update (5.3), the activity feature no longer is working correctly. The watch no longer tracks my steps or exercise. There is no data captured. I am also not sure if the stand function is working correctly, because it shows me standing every hour that I had the watch on. I am not sure that I actually stood up every hour.
I know when my watch took an update, it reset at that time, but I will do it manually to see if that works.
