Hey All,
I have previously used Google Drive for smartlinks / embedding files and it has always worked and displayed the full document.
I am trying to do the same with Dropbox links (the document is a pdf) and Smartlinks doesn't work, saying "We can’t display this link as an embed. More about Smart Links in the content tree"

Similarly when I paste the link into a page instead of turning into a smartlink (showing the title of the document and offering options for inline/card/embed) it just remains as the link.
Atlassian articles on smartlinks say this should work too.

Update:
I have tried this from Chrome / Edge / Safari - just in case it was a browser thing but it doesn't work on any
