I think this is missing, and it shouldn’t be. I have all the addons activated too. Am I missing something when I browse “Customizer” and search for submenu of primary nav?
The submenu typography inherits from the top level items, but reduces the font size a little.
I’ve found it’s very rare that people want to set a different font etc.. for the sub menu, and anywhere that I don’t have to list out those hundreds of Google Fonts I won’t – saves load time in the Customizer.
