Hello team,
We have observed that Seamless Single On gets broken due to the new sign in experience.
Behavior observed:
User with federated domain logs in Office 365 and closes he bowser (does not sign out).
If the browser is opened again, it gives a sign in page with remembered UPN instead of directly signing the user in O365,
This is not the expected behavior.
IE settings have been checked and we have added ADFS service name in Intranet Zone along with sign in URLs as well.
