Our swim workouts are presently not "structured" like our bike and runs are.  That means the specific details of the workout aren't being transmitted to other devices, just the whole chunk of the workout as one.

Because with the swims there’s no structure (only a time block), if you press “lap” you'll technically end the workout.

If you want to track your laps, when you start a workout, you'll have the option to “do workout”.

Scroll down to “skip” and do your own set, meaning you'll be able to press “lap” and record all the laps you want.

Then your stats will transmit properly.
