According to the following old issue, link counts should come back after a hard refresh page. But I’m not seeing this. Editing the post causes them to disappear forever for me.
No repro. I just edited post here on meta with a YouTube link that had a click count of one. After editing and saving the post, the count was still at one.
Here’s the post I edited
Could it be the other board is running an older version of Discourse?
Many thanks @merefield !
I’ll leave this open
