Okta Sign-In Widget not using Okta session cookie to SSO users

Hi,

We have implemented the Okta Sign-In Widget our custom portal (SPA using React), everything works fine using login password if we directly go to the portal.

But if we try to launch the portal from Okta dashboard we do not get automatically sign in as we should.

The portal is hosted on the domain “https://arteliaportal.arteliagroup.com/” and the custom URL of the Okta tenant is “https://customers.arteliagroup.com/” so the domain is the same and the session cookie should be shared.

Thank you
