Thanks for the response, somehow this is not the case for me. Like past times, I always hit the walled garden unless it's Facebook's actual Blog pages.
The provided link of https://m.facebook.com/story.php?story_fbid=1015993413146151... redirects me to https://www.facebook.com/login/?next=https%3A%2F%2Fwww.faceb... which is a hard auth page. No modals, no pop-overs, no X / bypass on the redirected page.
I tried the archive.is for content a work around on the share link, also didn't work.
