While social posts for webflow sites do populate with the existing webflow page OG settings, the facebook debugger reveals warnings.
eg https://developers.facebook.com/tools/debug/sharing/?q=https%3A%2F%2Fwebflow.com%2F
So a webflow site will get the following warning:
The following required properties are missing: og:url, og:type, fb:app_id
Webflow is creating manual error prone work for static pages where we have to add manual custom canonical url and now we need another for og:url.
