The cards on this page link to their corresponding collection pages when in Preview mode, but not when I publish and check the connections using the URL.
But it does look like it should work fine based on what I can see. Might pay to just try republish the site? Or check there’s no invisible element sitting ontop of the link blocks with inspect element?
Also check on inspect element that the link blocks do have the link set up? Just to ensure they are working.
If you can send a link to the live site without the password I’m happy to have a closer look. (Feel free to DM me as well if needed!)
