Hi everyone, I've come from Prestashop 1.7, I'm trying to remove the view of the left column in mobile view. At the moment when viewing on mobile the top of my page has categories and the products are way down the page even behind the store information. Is there some sort of hook I have to remove for mobile devices? Additionally on desktop view I only see 3 products across rows, however in feature products it displays 4 products. Is there a way to display 4 products? Ive looked through the settings and I couldnt find anything obvious, in saying that the thirtybees framework is a hell of lot easier to navigate. Thanks in advance.
