[keycloak-user] Keycloak 4.0.0.Final Implicit flow response is different to 3.4.3.Final

Hi All, In Keycloak 3.4.3.final when I used the implicit flow the URL fragment path contained: - session_state - access_token - id_token - token_type - expires_in - not-before-policy in Keycloak 4.0.0.Final I'm only seeing: - session_state - id_token - access_token Why is this? Is there configuration missing or is this a bug? Thanks, Ian.
