Hi @szaske,
I recommend reviewing our Sessions and Logout documentation for a detailed explanation of the different session layers when logging users out.
Next, I checked the Auth0 Swift SDK and confirmed the correct method to log your users out is with the clearSession() method. With that, I suggest checking your Auth0 Logs to verify that the user is logged out and that you can view those events in your logs. You should filter for the slo log event type code.
Ultimately, you must ensure that the user’s session is cleared before retrying the whole process again.
Thanks,
Rueben
