Did AuthO Remove Vittorio Bertocci's Learn Identity Videos?

Been meaning to check these out but the link just redirects to the docs root page and I can't seem to find the videos anywhere https://auth0.com/docs/videos/learn-identity/

The course description page doesn't mention the content being removed but again, the links from that page just bring you to the docs root rather than the videos https://auth0.com/blog/learn-identity-concepts-video-lectures-auth0-onboarding/#The-Identity-Course
