It's probably a lot less painful to backup dives through your phone.
This whole Bluetooth thing is a clusterf*ck. I'm amazed that something like this is an issue in 2017.
I agree. Fortunately my Perdix AI talks to my iPhone and iPad NO problem, and I DO have my dives on Shearwater Cloud. But as a matter of principal, I want to see if I can get Desktop to work - it should.
