Google profiles and logout

Hi all,
When switching between chrome profiles, our sso users gets logged out - instead of switching between their accounts. We store the token in localstorage, because we wish for our users to be logged in for 3 months when signing in. Many competitors work great on that front.
Is it a consequence of relying on JWT instead of cookies? If so, any solution on our end while using Auth0?

Cheers,
