I'm trying to do this on my iPhone itself. iOS 8.3 with iCloud photo library turned on. I created a photo album titled "other" to move some pictures from my main camera roll to keep them separate From all my other photos. Everything copied ok, but when I try to delete the newly moved pictures from the main camera roll it also deletes the same photo from the new "other" album. So I end up with duplicate photos. Am i missing something here?
