I've had my Venu 2S for about a month now. So far it's been great, but I've run into this problem twice now. The heartrate sensor will stop working about 0:1:30 into an activity. First it was with a hike and now was with a walk activity. Both times I didn't realise right away since I don't frequently check my watch on walks. After I end the activity it starts working again and the green lights are on the sensor. During the hike I did, I did take off the watch to see and the lights were all off. The watch has been updated since the hike but I just had this problem again today with the walk activity. Any fixes?
