We would like to know how to set that one of our free membership plans could be bought just once. We have a membership Plan Lanzamiento that has all characteristics of Premium plan and people could use them for free for 3 months. Then, when the subscription is over, user could select one of the three paid subscriptions available or stay with Basic characteristics.
So, we need this Lanzamiento plan could be contracted just one time per user. How could we do that?
