I tested it in the following procedures
- Set measurement interval to every 10 minutes in WFS project settings and uploaded it to the watch.
- I observed watch on my wrist for a few hours, heart rate measures and updates the value every 10 minutes as expected.
- I went into Samsung Heath settings, changed the interval to manual. After that, [HR] no longer updating heart rate value every 10 minutes until I trigger the heart measure from watch face.
[HR_IS_MEASURING] does get stuck on value 1 sometimes, even when the sensor is not measuring. Other than that, I’ve not experienced watch face freezes.
