I'm another person having issues downloading HR data from my Pro (ver. 7.10) to my 945 (ver. 5.50.00) when the devices operate independently over each other. It worked the first time and has failed all seven times after that. Garmin recommended a work-around of removing the battery for 5-10 minutes, allow the device to discharge and power it back up. That work-around didn't work. Anyone else have anything to try.
Having upgraded to the Pro from my Tri for the sole ability to use the HR strap independent of the watch, it was a complete waste of $130. Am I'm curious what's going on at Garmin that their new products continuously have software development issues?
