OK! Many thanks for the tips here!
raylock1 & JBC - bingo on the button! I found the exact screen you’re talking about. I have the Roger license 03 in both of my 312 aids. So WHY aren’t I able to use the Roger at all? Very strange.
My other pair of aids, Champagne, can not use this myPhonak app (unless I “forget” my primary pair of 312s), but with these aids I can use either Roger mic in any situation: in the cradle, or out.
I’m still in the 60-day trial period with these 312s, but it seems lame that I can’t even test the MAJOR accessory that I paid so much money for. My 2 Roger mics only work with the pair of aids not even controlled by myPhonak. 
PeterH: I see the three app-created programs you list (Restaurant, Music and TV) each one based on existing programs in Phonak. I already have a dedicated program for Speech in LOUD Noise, so should I eliminate “Restaurant”? Also, I have a dedicated Music program, so I don’t need the app-created “Music”. As for the app-created “TV”, I think that’s taken care of with my Roger mic connected to our home theatre box.
I think it’s TOTALLY COOL that I can either use my aids to cycle through the main 4 programs set up (Auto, Speech in Loud Noise, Music, Acoustic Phone) or, launch myPhonak and select these other three that have been pre-built for my use. In time, I may adjust and rename the other three programs to work in different situations. 
Now if only I could get the Roger mic working on my 312s. I was all set to REMOVE the license and then try to re-install it, but wonder if my audi should do it? Or should I live dangerously.
