I have a creative cloud subscription for myself and 2 other colleagues but cannot add the other 2 colleagues as users. How do I do this?
I checked you account and I found that you just have 1 seat in your Creative Cloud account. You need to add a license from the top right corner on your Team admin page.
You can follow the article: Creative Cloud Help | Manage your Creative Cloud for teams membership which will help you to add a license in your Team account.
Let us know if you face any troubles while doing that.
