At the top level menu, under Dorico, the command “Hide Dorico” is greyed out, and does not work; neither does the key command. It would be handy if it did.
Does it work for anyone?
It works absolutely fine for me. Perhaps you’ve moved Dorico onto its own “space” or are running it in full screen mode.
Yes, I was running it in full screen mode. “Hide app” seems to be optional in full screen. Some programs retain it (e.g. Firefox, Pages) and others don’t. Now I know which camp Dorico is in.
