Since today Facebook's og-scrapping doesn't work anymore (for ANY blog post – past ones that used to work including). No title, no image, no description. I can't upload always a picture with an URL – it's not good for the Facebook algorithm. And less people will read the articles.
Here are some example blog posts – more on switcherland.net:
Facebook Debugger: https://developers.facebook.com/tools/debug
As you can see it's not a problem on Facebook – Facebook can't scrape the right og-information from ANY Wix blog post. You can try it on your own with the examples above or ANY of my blog posts.
Screenshots Facebook Debugger:

Translation (more or less): Derived properties: The property "og:image" should be indicated even when another tag can be derived. Missing properties: The following properties are missing: og:url, og:type, og:image, og:description, fb:app_id And as you can see in the URL preview (GER "Link-Vorschau") there is no image (og:image) and my blog post title (og:title) appears as "Titel" (engl. "title"). Below you find the raw tags – I think they don't need a translation.

Example video: As you can see Facebook doesn't scrape og:title, og:image and og:description anymore. Just the images from the recent posts that appear after a blog post's end on the website (switcherland.net) and og:title (blog post title) appears as "Titel" (GER for "title").
Screenshots that prove that it used to work (facebook.com/switcherland.net): Everything was scraped correctly: og:image, og:title

Everything was scraped correctly: og:image, og:title

Everything was scraped correctly: og:image, og:title, og:description
