Google insists a page isn't mobile friendly

Hi everyone!

When I run a client site through the google mobile responsive checker: (https://search.google.com/test/mobile-friendly) it says that this site: www.emm.co isn’t useable on mobile because of content that is larger than the screen. The screenshot it provides isn’t actually of the landing page (as far as I can tell):

I’ve run through everything I can think off and still can’t make it register as responsive despite it performing fine on a mobile screen. Any tips would be greatly appreciated!

Thanks,
