I was told by chat this was possible, but I am not seeing how to achieve what I want to do. I am the administrator of the account and I need to give access to one of the users to purchase images under a suscription. I want to be able to purchase images as well from the administrator account if it is required. Is this possible?
According to this text I can assign the license to all team members, but I do not see the option to do it:
Creative Cloud for team administrators can select and assign Adobe Stock subscriptions to their delegates. Administrators can also choose to assign Adobe Stock subscriptions to one team member, multiple team members, or all team members.
Also, each individual within a team can separately purchase from or subscribe to Adobe Stock.
If you currently have a Creative Cloud for teams account you should be able to add a license for an Adobe Stock subscription via the Admin Console. If you purchased via a reseller they should also be able to order this for you.
With Adobe Stock pooled images, licenses that admins purchase automatically become available to all the team members. This feature is exclusively available for CC for teams customers.
Hope this helps.
