User Session Sync
Unfortunately (as of now) when a user signs up/in to any mapped domain, the user session doesn’t sync between the different mapped domains. All mapped domains should sync the user session (login/logout) so that when you for example signup/login on my.primary.com you’re automatically signedup/logged in to my.mapped-one.com. Ideally there would be a setting in “Domain Mapping System” to set which mapped domain will sync. I have no doubts that I’m not the only one who would highly appriciate such a feature.
