SSO w/Okta IDP-Initiated Workflow not Working

We’ve connected our Rancher instance up with Okta for SSO and found that the SP-Initiated workflow is working, but the IDP-Initiated workflow is not working. (Can click the login button from Rancher to login, but clicking the Rancher button from Okta is not working.)

Is this something that anyone else has ran into?

Rancher v2.5.8
