Like this one, that I'm seeing now? Maybe because it was at the bottom, I clicked on "more", then the duplicate showed up. But I click on "more" all the time. This duplicate thing shows up for me once a week or so.
I'm able to reproduce it right now, on a new page. This post continues to be at the bottom for me, then when I click "more", I get a duplicate.
Not seeing that but do see people sharing the same link as someone else but later and must be ignoring the dupes warning
Yeah we have a ticket for this
