The basic issue is that the web view component presented by the Google app on Android does not have the required _javascript_ features that modern browsers do, so the Duo integration fails if you try to maintain the session storage in the browser.

We're running version 7.2.7. Attached is a screenshot of the error message that appears immediately after a user signs in—before the Duo authentication prompt is triggered. Do you have any insights into what might be causing this? -- - Website: https://apereo.github.io/cas - List Guidelines: https://goo.gl/1VRrw7 - Contributions: https://goo.gl/mh7qDG --- You received this message because you are subscribed to the Google Groups "CAS Community" group.
