Since upgrading CAS apps are sporadically requiring users to login twice in a row. One of the app error log snippets includes the following. We are unable to reproduce the issue at will and hoping that someone recognizes this and can provide info. TIA - Michael

In our case the issue was primarily due to the apps utilizing older CAS clients, forcing the apps to update the clients.
