So, I have an iPhone 6S+ and an iPad Pro. In settings/photos/iCloud photo library, it's turned on in my ipad, but off in my phone. I take pictures with my phone and they don't transfer to my ipad. So, I go to turn on the iCloud Photo Library in my phone and it says it's going to delete all 5790 photos! NO!!!! So, how do I get them to talk to each other? And I'll need step by step, this one seems to have me a bit perplexed.
