Garmin 645 training status metric not updating when using Polar OH1.
It used to work a few months back but has stopped. The onboard HR monitor (though the data is often wrong for me) or using an external chest strap still updates as it should. Just not the Polar OH1 anymore. Has a recent update stopped external optical HR monitors from providing this data, if so why?
