Hello I have a user that is trying to Access Salesforce through Okta App, our org has SSO enabled and the user is able to access SF thorough Okta dashboard  web ,

Tried re-directing user using custom domain but everything is pushing user back to login page.

Note: User is able to access other applications on Okta mobile App however both Salesforce App and Salesforce through Okta are only re-directing him to the login page.
