I know I abvu by putting this here but it's for traffic.
I bought one of the above with a heart rate tracker and the instructions are dreadful and I can't find any online. Should the heart rate tracker be on continuously when I have it set to automatic on the app. I thought it should but the green lights on the back only come on when I tap the heart rate bit on the device. Help!!!
I don't want to complain if it's doing what it should be though
