Fix Video Link Share Bug

I run a video-hosting platform that works much like YouTube, and everything is solid except the “Share” button for copying a direct link to a video. When a visitor clicks it, no URL is produced at all—nothing to copy, nothing to send. I’m not entirely sure whether that logic lives in a custom snippet or an installed plugin, so the first step is confirming where it sits.

Here’s what I need delivered:
• Pinpoint the exact reason the share-via-link function fails to generate a URL.
• Implement a reliable fix so every video returns a valid, shareable link.
• Verify the solution across major browsers and on mobile.
• Leave me a concise change log so I can keep the feature stable during future updates.

You’ll receive access to the repo and a staging site right away, and I’ll sign off as soon as I can reproduce a working link on my end.
