I was wondering if this service work only within the same Team users account.
I have a client that would like to work and share the same project with me. But he has currently is individual licence.
I'm questioning if i have to add him as a new team member under our Team membership or if he can upgrade is own membership to Team...
Would the sharing could work for 2 different membership?
As long as you have a CCT or CCE membership, you can collaborate on a Team Project (you do not need to be members of the same licensed team or enterprise). See also FAQ: Who can avail the Team Projects (Beta) service?
But our client called Adobe and they told him a different story... They told him that we have to be on the same licence, so we gave him one of our one that we had left to be sure...
