I purchased the plan for $9.99 a month thinking Photoshop was included. When I download the software I get a trial version that I have to pay for in two weeks. Do you have to purchase the software separatly?
Did you download the Creative Cloud app and log in? It will show a demo until you do. If you purchased the Photography plan, check your Adobe account on adobe.com and make sure you are logging in with the same email you subscribed with.
If this all looks correct - you will need to contact Adobe Care to have them confirm your subscription details.
