To prevent malicious cookie tracking, Google Chrome 80 (scheduled to release on February 4, 2020) made a change in how cookies are handled in its browser. This change is expected to impact many applications including Dynamics 365.
If you have done customization and added an embedded iFrame in your application, the authentication for the embedded iFrame will fail. This is because the Google Chrome 80 change sets the default browser setting ‘SameSite=Lax’. This setting prevents the embedded iFrame to share the Dynamics 365 cookie from the main browser.
Your session will show a connection error.
