Ok… success!!

What you have to do is go to Settings >> Reading settings. There, set “front page displays” to whatever you’ve called your blog page which you’ve set to display full content. This does the trick! You cannot do it from the Customisation page, even though there appears to be that option there (it doesn’t work).

I did a bit more Googling and found this out myself. The key to doing it was in this post;

So why did your support team claim that it cannot be done, the theme isn’t written this way and I would have to hire a developer (having already paid for support from Themehorse). I think this is poor support.

It’s a shame because now that I’ve implemented this change, my site is looking a lot better.
