"Sorry, we were unable to retrieve information about your link" on LinkedIn

[Scubaman31]

I'm accessing LinkedIn and DropBox on a Mac Pro using macOS Monterey and the Safari Browser. 

I'm trying to add a "Media" link to my LinkedIn "Experience" section.  I click "Add Media" and select the "Add a link" option.  I then right click the folder I wish to share in the DropBox section macOS Finder, select "Copy DropBox link" and paste the result into the waiting URL box in LinkedIn.  LinkedIn thinks about this for a while then responds with: "Sorry, we were unable to retrieve information about your link. Please try another link."

This happens regardless of how I create the DropBox link ie directly via macOS Finder or indirectly via selecting the various share options viewing the same directory in my Safari browser.  I've even tried changing the end of the copied URL from dl=0 to raw=1 but get the same result.

I'm sure this used to work fine.  Anyone got any ideas?  Is it DropBox (I have a 2TB subscription) or is it LinkedIn (I have the free account).

Many thanks

Thanks for posting on our Community today, @Scubaman31!

If you open an incognito window on your Safari browser and paste the shared link there, you can preview it just fine, correct? 

If yes, then I’d recommend contacting LinkedIn next indeed, since this is regarding something that happens on their platform. 

Let me know, if you need something else though.
