Ever since I got my series 3 Apple Watch I noticed that when I start a workout such as outdoor walk, all the workouts in the workout app on the watch say “Open Goal” Unser the name of the workout type and the workouts are all green in color. On my previous series 2 I don’t recall the workouts saying “Open goal” and the workouts such as Outdoor walk were pink in color, the only workouts that was green was the “Other” Workout. I set up my series 3 watch as new so it’s not a case of a bad backup restored or something of that sort
