Service cards open their service page
Zarla now links a service card to that service's page when it can tell which page the card means, so tapping the card opens it.
A service card without a link of its own went nowhere when tapped, even when your site had a page for that service. It happened most on the Services page Zarla builds, and on the home page of some sites brought over from another website.
Most cards whose service has its own page on your site now open that page. A card you linked to another page or section stays put, and when we can't tell which page a card means, we leave it for you rather than guess.
There is nothing to set up: your live site picks the links up the next time you press Publish.
