For a Facebook video, you should be able to simply paste in the URL of the video, and the Block Editor will automatically convert it into a proper embed.
Well I tried posting the url of the video in a paragraph block and a custom HTML block and I did not get the video. What I got was “Posted by Oakview Baptist Church on Wednesday, May 20, 2020” No video. I also tried the <iframe> embed.
This was working. It just quit working. I tried it on a couple of other sites I own and used live preview with different themes still no luck.
Any and all help appreciated
Try pasting the URL directly into a new Paragraph block with no other content.
If that doesn’t work, what is the URL?
