iCloud Photo Library not optimizing
I turned iCPL, Photo Stream and iCloud Photo Sharing off in Settings/General/Photos &amp; Camera, rebooted her phone and then turned on all that I had turned off. The phone then showed a spinning gear for about 5 minutes saying "Turning On" and after that I went to Settings/General/Usage/Manage Storage, and saw that her phone regained 2Gb of storage back from only having 388Mb available. I did not have to delete all of her photos after I turned iCPL off.
