Hi guys, unfortunately, we have an issue with the link preview on this Facebook Page: https://www.facebook.com/DieOberbadischeVerlagshausJaumann

I already had the domain verified (verlagshaus-jaumann.de) and linked it to our Business Manager and the FB page, but this didn’t really help.

The sharing debugger shows the follwing error code 206: The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.

Can some one point me in the right direction? Our Dev-Team didn't see any issues on the HTML.
