The function definitely works but it only removes the secondary nav from the homepage.
When I tried the CSS method it definitely worked but won’t show the secondary nav on anything BUT the main blog landing page. The individual posts hide it.
I feel like there’s still another missing piece. Essentially: having the secondary nav show on all blog pages, not just one archive page. I’m digging to find the additional classes for the category archives & individual post archives but I feel like there’s another way to do this with a single function, no?
