I just subscribed to Lightroom plan with 1TB to see how it works. On my iPad, Lightroom and Creative Cloud apps are installed. On my Mackbook pro is Creative Cloud installed as well. I did one test and edited a image in Lightroom on iPad. The image has been automatically synchronized to Cloud Storage, and when I open Web Lightroom on my Macbook Pro, I can see the image under All Photos.
But I am surprised that I do not see the image in the Creative Cloud app on my Macbook. I checked Your files and Your Libraries, and both folder are empty. When I click on Cloud icon next to Profile icon, it says Cloud Storage 35 MB of 1 TB used, so that the image must be there. Why the file is not visible ?
Good question and thanks for posting. Files uploaded using Lightroom do count against your storage but are stored in a slightly different location than libraries in the Creative Cloud desktop app. You can access this location in a browser at https://lightroom.adobe.com
