Can't upgrade app from trial despite already owning plan
I have a Creative Cloud Photography Plan which I am appropriately being billed for. However, my desktop Photoshop app doesn't recognize that I'm signed up.
The Creative Cloud app shows that I am not paying for Photoshop CC:

So I click on 'Buy Now' to buy it:

But it tells me that I already have the product:

Help? I've tried uninstalling and reinstalling the app, and I've deactivated the device which was linked to my account, hoping that it would proc my PC to activate itself. Nothing has changed.
Thanks
