I have the Instinct 2 and an HRM-Dual. I have paired the two devices and have confirmed in the watch that it is connected. However the watch does not appear to be reading from the chest strap at all. I have confirmed through a separate app that the HRM-Dual is working and is accurate to my actual heart rate. I've also confirmed that the watch is not displaying what the HRM is reading.
Thanks for any help.
