We have 11 seats that we are sending to the team here and I am trying to understand what they need to do so they can download / register the apps. I sent out an invitation to one of the team members and it's asking him for an Adobe ID. Should this be one that he registers on his own or the admin one? There isn't a "Register an Adobe ID" or anything like that under the form that he's lead to from the invite email.
Welcome to Adobe Forum,
The Adobe Id will be the e-mail to which the invite was send. few of them who accept the might not have the password, that needs to reset by clicking on " having trouble to log in/sign in".
