Anyone want to take a stab at this?
I have two themes installed. I have two menus created. I'm using a theme switcher to load theme 1 for desktops and theme 2 for mobile. I'd like to display menu a with theme 1 and menu b with theme 2.
But... menu b doesn't show up on the mobile view when theme 1 is the primary and conversely menu a doesn't show up when theme 2 is the primary.
Menu b shows up when I make theme 2 the primary but when I make theme 1 the primary and use the switcher it doesn't.
