A previous post describes my situation perfectly but it has not been fully answered almost 2 years later. Here is the post: Confused about iCloud and iCloud Drive
I believe that ios and MacOS apps syncing to iCloud Drive is what's causing my iCloud Drive to state I'm using 90 GB when I can only account for 50 GB actually stored in my iCloud Drive. Why would Apple not allow me to inspect the full contents of my iCloud Drive? Current state I'm not able to manage the storage because I'm unable to see how much space each app is taking up in my iCloud Drive.
