Hi, there's a message by Ritesh Garg dated May 25, 2018, about Offline Tokens becoming invalid when user sessions are logged out via Admin REST API. (I just joined the list, so I cannot easily reply to that message directly.) The issue is still reproducable in 4.5.0.Final and also affects the User Account app (when the user clicks "Log out all sessions", Offline Tokens cannot be used anymore). I created KEYCLOAK-8638 for this. Cheers, Mario.
