After last week's update to Vivosmart 5 my heart rate data (being broadcast to my Edge Explore 2) often flat lines after an intense effort and does not drop back again (see screen shot below). I have to stop, end the broadcast from the Vivosmart and then restart the broadcast. The Vivosmart seems to be recording the correct heart rate all the time, but something is clearly awry with broadcasting to Edge Explore 2.
I've washed the Vivosmart and do not have any sunscreen or other goo on my skin and I'm wearing it in the correct place. An ideas about what's going on?
