In my PC's Windows 10 Pictures folder there is a ICloud photo one with 3 categories namely Download/Shared/Upload, when I want to copy some of these images to my Iphone I receive the message "Cannot Copy Item" device has either stopped or not responding. Yet my Iphone is recognised in Itunes as well as File Explorer. Also the "Send to Iphone" will not respond. I find the ICloud site (App for Windows download) is basically a static page and cannot be used for viewing files (only their size) I am now very confused as to what to do.
