I’ve had my watch for about a year and a half and lately it’s driving me nuts. First the heart rate monitor isn’t working correctly. I’ll be riding my bike and my heart rate should be reading between 140-160 but it shows around 90. I have to hit start and stop on my workout, sometimes 2-3 times, to start reading correctly. It’s snug to my wrist, I’ve restarted multiple times, I’ve cleaned the sensor multiple times. Anyone else experience this?
