Hi! I use the Photo Library Beta on my iphone 6 and iPad mini 2. When I Switched it on on my iPad, it had no photos stored on it. On my iPad I switched on, that it optimizes Photos, while it has to keep the Originals on my iphone. Now Photos take up 8GB of Storage (and won't free them when I need Space) on my iPad and I'm wondering how to delete photos from my device, but not from the iCloud library, like I used to Do it with iTunes Match. I hope you can help me!
