Inaccurate Storage Space
The amount of space within the Creative Cloud seems to have been moderately accurate, yet after deleting items it seems to never decrease, leading to inaccurate readings on available storage.
Thanks for reaching out. Depending on your plan, Document Cloud & Lightroom quota might contribute to your overall quota (in addition to your Creative Cloud quota), which is why your Creative Cloud quota shows up as a fraction of your overall quota.
