I never got it working. I think the issues that affect Lites also affect the full version too. There was a Build a Big Band Discover Dorico session a month ago where John Barron mentioned that there will be an update from Fable that will hopefully fix the notation mode issues, but it still hasn’t arrived.
I don’t have Atomic Big Band, but it is discussed, along with a lot of other libraries, in this thread if you haven’t seen it. @RobinHoffmann has Atomic BB, so maybe he’ll chime in and offer advice with it if you are interested.
