Hi @lvillacin,
These issues are usually related to third-party cookies. In Safari, Intelligent Tracking Prevention will block the cookies that Auth0 uses to persist the login between browser sessions (tabs, windows, etc.).
Our solution for this, as you have mentioned, is to use Refresh Token Rotation. You can use this for all of your Authentication sessions, regardless of browser, and don’t need to use it conditionally based on the browser/user-agent.
Thanks for the input and let me know if you have any questions!
