If you've updated a link on your website and published, but it's not updating on the live site, you can try one of the following solutions:
Refresh your live site by holding down the shift key as you refresh the page. You could be seeing a cached version of your site and refreshing while holding down the shift key helps clear browser cache.
Check to see if there's an additional link placed somewhere else. This is a pretty common occurrence since a link can be anywhere on your page. You can have a link placed directly on text like this:
You can see here that it's the correct link, so that's not my issue. Next, check the text element to see if there's a link there.
You can see that the text element has the wrong link placed on it—it should be going to /best-practices not /interactions. You can remove the incorrect link by clicking on the trashcan to the left of the link in the black bar.
If the text element or text itself doesn't have the incorrect link, or if removing the incorrect link doesn't fix it, then keep going up one parent element at a time using the breadcrumbs (where it says Container/Text under the black link bar) until you see an element that has the incorrect link for you to remove, like this:
Since this parent container has the wrong link placed on it, and probably shouldn't have a link at all, we can remove it and publish the website to fix the link issue.
