Hi @srocke , welcome to Auth0!
A known case where users are directed to the login page while being already logged in is when the /authorize request is sent with the optional param: “prompt” having value other than “none”.
with: prompt=login, users will be shown the login page regardless of being already logged in.
Can you maybe inspect via the browser network tab what params are sent with your /authorize request payload? Ref for available params - AuthorizationParams | @auth0/auth0-react
