Your plugin hasn’t recycled all of my posts yet, so not sure why the social auto posters have stopped all of a sudden.
But, I was researching jetpack publicize troubleshooting (I wasn’t using jetpack’s social publicizer before) and they suggested I ask you this.
By the way, thank you for your patience.
Using a Post Duplicator
If you use a plugin to duplicate your posts, you could run into issues, because as well as duplicating the post content, it will likely also duplicate the post meta that tells Jetpack that the post has already been Publicized, so when you publish the new post, Publicize will fail.
There are several possible solutions for this:
Don’t start from a published post. Duplicate a draft post.
If the plugin includes an option like “Don’t duplicate post meta” – enable that option.
If the plugin doesn’t include that option, ask the plugin author if they included a filter to prevent duplicating the post meta.
If there is no filter, ask the plugin author to exclude all post meta containing the ????_wpas???? string from ever being duplicated.
