I'm very happy with the Neutro theme except for the fact that when I reduce the size, or view it on a smaller device, the menu disappears. I'm using the secondary menu as my main navigation because I want the coloured strip. At smaller sizes the colour I've chosen changes to the default blue of Neutro and the menu items are replaced by a link 'Menu' which should show the items in a dropdown but just seems to refresh the page. This doesn't happen in the demo site so I must have something in mine that's causing it but I can't see what. I'm not using a child theme or custom css. Can you help please?
