Issue:

Users reported an issue viewing YouTube videos embedded in Canvas pages. The videos were not displaying as expected, and the embed code was stripped from the page.

Related Information:

Canvas engineers adopted a permanent security decision to block certain HTML tags/elements in the rich content editor (RCE). The referenced tags are "data-url", "position: fixed", and "position: sticky". Their HTML Allowlist has been updated to show all HTML that should be allowed within the editor.

Canvas Community Post: Youtube videos are gone and Additional community thread

Resolution:

Canvas engineers applied a fix and restored YouTube content using the allowed HTML embed coding. If you come across pages with missing embedded YouTube content, you can manually copy the YouTube video information and replace the HTML code.

If you have a large amount of content (across multiple courses and course items), please provide a list of that content to support additional work by Canvas engineers. Email help@tulane.edu and attach the list of courses. Use the subject line #ILC Restore Canvas YouTube videos.
