This has only happened since the 9.60 update with the new strength training UI. I am not a fan.
I have workouts on my watch. When I use them I want to see the countdown of my rest between my sets. Every single time I have to scroll through the entire setlist to get to the time screen. I do a set and it takes me back to the set screen where I have to scroll through the set to get back to the timer which, by then, is halfway through. Why doesn't it just stay on the same screen during a workout? It's not in the settings anywhere!
