Issues with Metadata Previews / Redirect Behavior When Sharing External Link Aggregator Pages

Hi everyone,

I’m seeing some odd behavior when sharing external “aggregator” pages (pages that collect multiple invite/group links), and I’m wondering if anyone familiar with how the Audacity Forum or its software handles link previews can shed some light.

Here’s what happens:

I run a page like this (non-static, redirect-type): https://justgroup.link/online-earning-whatsapp-group-links/

When I share one of these links (in chat, notes, or on the forum), sometimes the preview (title, image, description) doesn’t show.

The redirect also doesn’t always work as expected — sometimes it won’t open the target app, or just gets stuck.

What I’ve already checked:

The page has proper Open Graph tags (og:title, og:description, og:image).

Redirects are set up correctly on the server.

The target apps/clients normally support this type of redirect.

My questions:

Could the Audacity Forum (or the way it handles previews) be blocking metadata for dynamic/redirecting links?

Could it be due to preview caching or how the forum scrapes metadata for posts?

Are there certain headers or security/privacy settings that need to be present on external sites for previews/redirects to work correctly here?

If anyone’s run into similar issues (broken previews or redirect problems with aggregator-style links), I’d love to hear your experience or any fixes you’ve found.
