SSO Error using two SPA

Hi there,

I’m really excited to start using the Auth0 in many of our systems. Just yesterday we delivered an application with the authentication part integrated to Auth0. But I identified that the SSO is not working. Let me show our topology.
We are using Two SPAs with VueJs, authenticating to one application and asking for credentials to one API, same audience, claims and everything.

When I login in the first SPA, was expected to also don’t ask for login in the second one, but this isn’t what happens.

The problem can be the SPA requesting logins for the same application in Auth0?

A draw of the topology:

All the Cookies and data is been set in the Auth0 Login screen, but the login prompt always shows.
