I also have this issue, though I can’t be sure it was after an update
I can confirm this as I also had All-in-One SEO going. With that turned off and Yoast on, everything is fine.
Thanks Shannon and Michael!
Thanks. Would it help if I turned the plugin back on and pointed you to the page where it’s happening?
Update – I’ve noticed that, at times, if I post a new item that will appear in a feed, the short code seems to work for a day or two. Might this have something to do with it?
