Hi @judith1
Welcome to the Auth0 Community!
Hopefully the advise that @vigneshSivasamy proves useful in solving the issue for you, we appreciate the implication here! Also, do make sure that you enable " Show as button" so it does show up as a login option.
Depending on what works best for you, one option can also be to establish the Azure AD Connection through a SAML Enterprise Connection, toggle on IdP-Initiated SSO and enable “Display connection as button” under the Login Experience tab. The following Knowledge Article can be useful in this setup if it’s a good fit for you.
Let us know how it goes!
