Some files in iCloud folders refusing to be moved around (to other folders)
In an iCloud folder (KEYNOTE), some files (PDF, Keynote) just won't allow me to move them into any other folder. I try to drag and drop, but once I bring the file into another folder, I see the "circle+crossed line" icon that tells me I'm doing the forbidden. I CAN move some files (also PDF, Keynote), and some I just can't.
It also doesn't seem to matter whether they've been downloaded to my computer or not.
Sharing & permissions are set the same for files I can move and files I can't.
What's going on here? How do I fix these files to make them movable?
Thanks!
