I configured Microsoft Entra ID as my federated identity provider, but it doesn't appear on the sign-in page. What should I check?
Verify that the issuer URI and well-known OpenID configuration endpoint are correctly configured. An incorrect issuer or discovery endpoint prevents the identity provider from appearing during sign-in. Also check that:

- Configuration changes have fully propagated. Re-saving or recreating the user flow after configuration changes often resolves this issue.
