This isn't the only irritation I've had with this watch.
Setting watch displays can only be done through the mobile app, and they don't define the difference between "laps" and "intervals".
When snowboarding, it doesn't ignore vertical ascent (usually on a chair lift), so it records high TSS for the activity. It also fails to accurately count the number of runs you made down the mountain.
When lap swimming, it also can't count pool lengths reliably, over-counting by dozens.
