I was actually able to get this to work. Turns out it was an issue with my tenant in Auth0. I was able to delete and spin up a new tenant and all worked fine.
Is there any plan for this same tutorial but with JWT instead of cookies. Specifically looking for help getting a solution for Blazor Web App with a razor class library shared with a blazor hybrid maui application. All would be calling a web api so thus need to make tokens work.
