With new upgrade looks like the response time between the phone and watch is slower! So when I start my running the Watch app still thinks I have not started and sits at START does not move ahead. Your switch between wireless and network 4g is not smooth. It logs me out from wireless to 4g switching every time. You have to keep me logged in. Lot of time waste in trying to login etc.
