Why is apple watch missing laps in pool swim?

Hey there Cownslur122,

Here’s how you can get better results when swimming laps:

Your Apple Watch estimates your measurements during workouts based on the information that you entered during setup. Here's how each workout is measured: 

• Pool Swim: When you start a workout, be sure to accurately set the pool length to help your Apple Watch measure laps and distance. GPS isn't used during a Pool Swim, and water might prevent a heart-rate measurement, but calories, laps, and distance will still be tracked using the built-in accelerometer.
• Open Water Swim: GPS will only provide distance when you do a freestyle stroke. Water might prevent a heart-rate measurement, but calories will still be tracked using the built-in accelerometer.
