Hey guys I am not sure if this has been started yet or not, but the last two morning I have been using the workout app on my Apple Watch while in the treadmill. Both times I was on it for 20 minutes. Yesterday it told me I exercised for 14 minutes, and today it says 7. I don't understand. I am starting and stopping it when I start and finish, and the time is 20 minutes. Has anything seen this before?
