And so I enabled iCloud Photo Library on my Mac and took about 3 days for it to upload all my pictures from my Mac to the iCloud Photo Library. And so now on my iPhone, I just enabled the iCloud Photo Library. My question is how long it will take before all the pictures in my iCloud Photo Library will show up on my iPhone? Do I have to be connected to wifi for it to happen? I thought the pictures will show up instantaneously on my iPhone but not seeing any movement or changes. Please advise. Any help or suggestions will be greatly appreciated. Thanks.
