Honestly, @art.stupels have you used that?
Auth0.js is poorly explained over docs. Docs are generally confusing and not to the point. I tried with the logout docs, as we also had a problem that people were always logged in. Good luck configuring it based on docs. You can read 10 pages and still not learn anything…
In short, if you need Auth0 you have to have someone who is dedicated to it full-time and starts a month earlier than the rest of the team. Or simply someone who has already done 10 projects with Auth0 (somehow).
I do not understand why Auth0 is offering a free tier and address smaller project issues if there is no room for those.
