Heart Rate Undetected on ONE activity
Doesn’t detect the heart rate with open walk activity but it works for all other activities.
Apple Watch Series 3, 5
In my case I believe there is an issue with starting a workout when you are listening to audio with a bluetooth head set. If I start my workout while listening to audio on a bluetooth headset it is hit and miss as if the heat rate is reliably recorded. It is much more reliable if I start my Outdoor Walk first then wait to connect my AirPods to listen to a podcast till after the Workout app starts to register the heart rate.
