While the app does go on to allow us to get the accountID and everything, this does seem to keep us from showing to the user that they need to restart for policies to apply. Is this expected now?

To Reproduce call loginAndEnroll and you will see the above when the "checking" step in the login happens in the console output

Expected behavior: I shouldn't see this in my console
