InDesign-generated PDFs fail for URLs

InDesign 18.4/Mac.

I have 200-page InDesign file with a number of URLs going to weblinks. The URLs look good (select link text, right click>Edit Hyperlink. Link to: URL; the destination is correct and includes the full URL. When I right-click Go to Destination, they work perfectly. The InDesign-generated PDF file, however, doesn't work properly. What it looks like: If the tip text is the literal URL you want to go to (https://www.website.com), they work. If the tip text is "go to our support website" with the linked URL being https://www.website.com/support, the link does not work--it's shown as a URL, as it's in hyperlink character style, but mousing over the linked text just shows a Edit tool rather than grab tool and the linked URL. I've never seen this problem before, and have no idea how to fix it!
