free session for users with link

Hi, we used to have free session - ie. session with free access with no registration/waiting room just for people with link. One used to have host code to claim host rights. Now it is possible no more. Every session with no regitration required, with no waiting room still requires host to start the session - future host rights claimer has no chance to join to claim host code. 

With feature "passcode" or "invite link" it is not possible either. Invite link directs you to waiting something and passcode you cannot fill anywhere....

Any idea how to make the simplies session with no annoyiing login features?

Thanks!
