Yesterday during the "Indoor walk" workout I have noticed that green lights (heart sensors) are always on.
I have restarted the Watch, but as soon as I open Workout application, the lights are permanently on: during some 20 minutes exercise, they switch off couple of time just for 2-3 seconds.
Please help me understand what is the issue?
I do exercises almost every day, and it is the fist time I see them permanently lighting.
Both iPhone and Watch are up-to-date with last software
