When I'm not logged in to my Adobe CC account and I view this page (Adobe Stock - high quality royalty free stock photos and vectors | Adobe Stock) I can see an option for bundling Adobe Stock with my existing Creative Cloud Subscription. There's a button to sign in just below that. When I click the button and login, I'm returned to the same page. Except nothing has changed. The "Already have Creative Cloud?" section is gone, and there's no option on the page to bundle Adobe Stock with my existing CC subscription. What am I doing wrong? Is there some restriction on my account that I'm not aware of?
As you have a CC Teams account you can add the Stock license via the Admin Console - Manage your membership and payments | Adobe Stock - see section "Upgrade your Creative Cloud Membership to include Adobe Stock Membership > If you already have a Creative Cloud for Teams membership"
