I have a Fenix 6 running 4.1 fw and Jabra Elite Active 65t ear buds. There is a new (late September 2019) fw for the ear buds that makes the connection process work better for me. When you start the run activity on the Fenix 6 it will ask if you want to pair the Jabra buds as a foot pod. I found that every time I did that I lost connection for music so I assume it is one or the other. I therefore deleted the foot pod association and just use them as phones. As I use an HRM-TRI for running metrics I am not really interested in the foot pod.
However, the Jabra fw is a good step forward - no pun intended
Hope this helps people
