The heart rate monitor of my adventurer stops randomly during rest. When I go to an activity when it has stopped it doesnt start (leds stay off). Only when I go to settings>sensors>heart switching it off, go omd step back and then beck to heart to switch it on, it works for a while in rest and keeps on working during activities. It has firmware 1.7.53 and I tried factory reset which didnt help. Tomtom suggests sending it to them to replace the sensor but I have doubts if it is the sensor itself. The watch is barely half a year old.
Anymother suggestions than sending it for repair?
