Hi Matthew and welcome to the forum. The problem with the menu displaying on your iPad mini is a known problem and is unlikely to get resolved in the near future. Having said that I've just looked at my own site on my iPad (not mini) and its displaying the entire home page without the menu in landscape and portrait correctly. So I don't know why that has suddenly fixed itself - but not for you.
Below are my settings for the home page which are under Administration/Main Setup, scroll down to 'Desktop and Mobile homepage.
