Hi, @c77. What is exactly not working? The more details you explain about it, the better support we can provide.
Note that the free version lets you share on social media the posts (and any other content) you’ve created on your WordPress site. In particular, you’ll be able to share one message per profile when a new post is published, thus promoting it with your followers.
In the premium version, however, you’ll be able to share several posts after a post has been published (that is, at the same time it’s published, one hour later, two hours later, the next day, and so on), as well as create any other social publications in the Editorial Calendar. Moreover, it lets you connect multiple profiles from the same network and a few more other advantages.
I’m sorry if you weren’t able to get the plugin up and running. If you want to give it a second try and need some help, please let me know and we’ll be happy to help you.
