AirPod Pros and (2) Air-Fly Pro??

[tcuprof]

Anyone using AirPod Pros with an Air-Fly Pro? I want to use my Air-Fly Pro with my Denon receiver so my wife and I can listen to TV with our AirPods. I can get one set of AirPods connected to the Air-Fly but cannot get a second pair so connect. The Air-Fly manual explains how to do this, I just cannot get it to work. So, I wonder if there is something I'm doing wrong.
