Since ProPhoto does not have much in the way of customizing the mobile view for P5, we have used a nifty shortcut.
By using a page we are able to spruce up the homepage.
To edit the text shown on your mobile homepage, navigate to Pages > House of Grey - Mobile
Here you can edit your text as well as social media links. Save the page once finished!
And always make sure to double check your mobile view for demo logos and links.
