I have more files on my iPad than there is room for on iCloud. Therefore there is not enough storage on iCloud. I have increased storage once, and doing it again is out of the question. How do I delete photos/videos from my iCloud storage? I have them stored elsewhere and I need the room on iCloud. I have "shells" of apps on my display showing the word "Waiting..." which indicates that they are waiting to be completed for lack of room. Please help.
