Thank you for your response! I tried a suggestion from a feed I’d read yesterday and it worked!
Basically, we connected and then switched his driver on the computer to generic and then back to Focusrite and this caused it to work.
An interesting observation was that I could not manage his side, Master, Studio, VST, etc… it wasn’t even visible on the Connect Pro side. But it still worked. I just had to ask him to make input/monitoring adjustments on his side to his liking. My Cubase 8.5.20 crashed midway through the session while I was performing something in VST Connect and we had to go through the routine again of switching drivers back and forth on his side to make it work. The second time however, allowed me access to his controls, master, etc… go figure.
