I continue to have the same problem with an iphone 6. 90% of the time I can't BT sync the activity I just finished. Sometimes some combination of rebooting phone and/or edge and/or turning off and on BT works, but nothing appears to be consistent. All the latest software. I'm sorry to say it is almost always been this flakey. (And don't get me wrong, I love Garmin and have many garmin items. It is just this has never worked well for me and is a frustrating way to end almost every ride).
