Hello! Today I decided to activate iCloud Photo Library on my iPhone and iPad. I didn't have any cloud options already activated for the photos (for example, no Photo Streaming). Anyway, after activating iCloud Photo Library, also the other options activated: Photo Streaming and iCloud Photo Sharing. So, first question: why both iCloud Photo Library and Photo Streaming activated? I know that they are different, but I thought that activating iCloud Photo Library would have turned off and greyed out Photo Streaming. So, can I use both of them? Is it useful? I decided to turn off after some minutes Photo Streaming and leave on only iCloud Photo Library: is that a good move or should I leave both on? Also, in my iCloud backup there is still my photo library: since I'm now using iCloud Photo Library, will it automatically turn off or should I do it by myself? Last question: I'm currently uploading iPad photos. After the upload finishes, will the photos appear also on the iPhone? Together with the iPhone's photos or in another folder? Thank you very much and sorry for so many questions!
