Listing not displaying on mobiles

I have AgentPress Pro installed and the Agentpress Listings. When I share a link for a listing in Facebook, it displays the homepage instead of the listing. In fact, lots of URLs seem to default to the mobile homepage.

This is nothing to do with Facebook as I checked the link with the Facebook debugging tool.

How do I fix this? Either by identifying the reason for the default homepage view, or by getting the site to display the desktop homepage rather than the mobile version.

Thanks,

Alex
