I have the TomTom Runner 3 (serial number beginning with HQ), and I have never been able to record or see my heart rate since purchasing it a couple years ago. On the watch, I've gone to "sensors" > "heart" > "on" and clicked through. The heart rate is not found under "Progress" on the website or app. It reads "--" above heart rate. Please help.
