Access token refreshing after Tenant session timeout

@markd Yes. I am using a refresh token. Does it not sound weird that the user who issued the refresh token has now an invalid session in AUth0 but the refresh token is still valid?
If the user has already logged out from Auth0 or the session has been timed out, how can I know in my app that it has happened? How can I verify that the user is logged out without redirecting to Auth0 so that I can log the user out from my app too?
