IMO it’s a terrible idea to have the “skip interval” button right next to the pause button. I have accidentally hit next instead of unpause while bouncing around on my training too many times. Can’t be the only one.
I actually only learned this past week that the Tab button… for doing the laps feature, is also the skip interval button 
Hadn’t realized or knew that the feature didn’t work when workouts was running…
I’m not sure I’ve noticed the skip button, I’ve always swiped on the workout screen on companion up until now.
