The lesson represented by this video: https://www.epicweb.dev/workshops/authentication-strategies-and-implementation/redirect-cookie/handling-redirects/solution at http://localhost:5639/21/03/solution does not show any progress. The option to mark it as complete is not present in the local app. It's also not showing up at all in /admin. Not sure what's wrong here.
