Before going on holiday, I got this by email from WordPress :
“Starting August 1, 2018, third-party tools can no longer share posts automatically to Facebook Profiles. This includes Publicize, the Jetpack tool that connects your site to major social media platforms (like Twitter, LinkedIn, and Facebook). Will this affect your ability to share content on Facebook? It depends. If you’ve connected a Facebook Profile to your site, then yes: Publicize will no longer be able to share your posts to Facebook.”
So, in order for my blog posts to automagically be posted to FB, I’ve created a page: The Beaver Is A Proud And Noble Animal. This is where my posts should appear from now on.
