Why does the optical h/r sensor in my F5 turn off?
If I enable it on the watch, it seems to turn off after a short while. The only thing I can think is that Garmin connect on my iPhone 7 synchs with the watch and because h/r is not turned on on the iPhone, it pushes that to the watch and turns it off.
I thought synch was meant to go both ways, where the most recent change on either the watch or gc was replicated in the other?
Anyone else have this?
Thanks.
