I've noticed something I think is a bug. When looking at post-workout data, the HR zones for the HR Chart screen aren't color coded based on custom HR zones. I've included a couple examples.
You can see that for both workouts, the Zones screen shows (correctly) that my HR was mostly in zone 2. But on the HR chart screen, they both show only momentary blips into zone 2, and are color coded almost exclusively in zone 1. I believe the chart seems to be showing preset or device derived HR zones, rather than the custom sport zones I've input.
I'll have to double check, but I believe it's doing this on the HR chart data field during a workout, too. I don't usually use that one though, so I could be wrong.
