In reply to Daniel.

The navigation close button sort of works when I tested those sites on mobile on both Android and iPhone. I say sort of because a light touch seems to do nothing but a very slightly longer press does close the navigation.

Interestingly when I install Frost on one of my own test sites, the navigation close button works perfectly with only a very light tap. Don’t know what is different in the setup on those sites mentioned.

Hope this helps.
