I still haven’t found a practical use for it.
This morning, my watch alarm went off. Tried to double-tap to turn it off. Since my watch is still in Sleep Focus, the screen doesn’t turn on, so the double tap doesn’t register. I had to press the crown to turn the screen on, and then the double tap worked.
During a workout, a double-tap to pause would be nice. But no actions register during a workout.
It’s gimmicky.
I used Quick Actions for a few weeks on my Series 7 and never accidentally paused a workout. But since it does work to pause a workout, it was really nice being able to do so when I had the feature enabled.
What was far more likely to happen was I double-pinched in an attempt to pause, but nothing registered. This generally happened when I wasn’t standing up.
I’ve never seen an option to pause the workout, only unpause. Are you sure you’ve paused the workout before?
