I know there's threads on the change to how it works with the stop watch but I noticed it has also changed for any activity in which that activity has touch screen switched off during said activity.
So for example I have touch screen off for running, but with the current software version (21.20) once I select Run (or any activity which touch screen is off for) from the activity list the touch screen is immediately disabled prior to pressing start.
So this means you can't flick up or down your daily suggestion or selected workout etc using the screen. Unless I'm gone mad you could always do that using the screen and only when you pressed the start button was the touch screen disabled.
