SSO not working Edge

Certified Associate Developer

We have issue with logging into Appian via SSO only on Edge browser. Where as the same working on IE and Chrome. The same SSO configuration worked even on Edge when we configured. It stopped working from this week.  No changes are done to the SSO configuration in Appian / IDP side since it was working.

Looking for help.
