I created a custom workout on the web to imitate the effect of the daily suggested workout on a stair steeper. When I selected the custom workout on my watch, the device asked me "Choose an activity", I chose "Stair Steeper" and I started the activity. To my surprise, the GPS was activated and one of the Data Screens was showing me the map which was unnecessary and a waste of battery. I have already my Stair Steeper settings to see if I had the GPS on, but this profile doesn't even allow you to activate the GPS, so I think what happened it's a bug? I'm in version 9.36.
Also, the interval training sessions from the daily suggested workouts usually skip the last "Recover" period from the session and goes directly into cooling.There should be an option like that whenever one creates a custom workout and use the "Repeat" feature.
