I just wanted to give you a quick update on the YouTube links issue.
Looks like Embedly status page is not reporting an error with embedding YouTube links anymore, and I was able to test some YouTube links again successfully.
There is still an open issue with using the YouTube links in rich text elements, and also using the YouTube short version (eg. How to Webflow: Adding a progress bar to the Webflow slider component - Tutorial (2019) - YouTube) and the team is working on a fix for this.
But otherwise the other areas for embedding YouTube such as the video embed, the YouTube embed and the video link fields are working at the moment with the full YouTube video address (eg. How to Webflow: Adding a progress bar to the Webflow slider component - Tutorial (2019) - YouTube).
