Auth0 SSO and SAML with Tableau

We have used a SSO solution to have Single Sign On between Custom SPA website and Tableau using Auth0 as IDP (UserName-Password)

This configuration stopped working 2 weeks back and when we try to replicate the issue currently, we see that the solution is working.

Is there any change in mechanism for SSO and SAML for tableau in recent times from Auth0?

I took a quick look at the history and although it’s not the same exact timeline there was a regression introduced in early October that impacted some SAML flow edge cases; this was then detected and fixed. That would be the only thing that I’m aware that could explain that situation.
