Hello persyst,
I’m not sure I can help you much with this, sorry!
From what I understand, after a submitted post is published, it’s as equal as all other posts. I even check through the html of the two events, to see if there were any major differences, but found none.
I know it doesn’t help much, but it might be an issue with the sharing plugin, maybe? I’m not sure why it could parse one page, but not another.
Do you have another example of the share feature not working? It might be helpful in tracking down the problem.
Cheers!
