I'm having the same issue.
What is the URL of the video? It's a vimeo link to an unlisted video. I can't add it here because it's private content.
What is the URL of the website? www.keycollage.com, but video is behind a paywall
How are you adding the video? Using a Video Block, an Embed Block or a Code Block? using a video block
Are you using the video URL or the video embed code? using video link. Right after adding link I see the message "video found and ready for use" But then all I see is "Unable to load video. Try again later" all the video settings stay grayed out.
