Media browser does not show most photos under iCloud Photo Library
I use iCloud Photo Library. I've got 50GB of iCloud space, and I'm using only 17. My device has 2.2GB of local space free. And yet, when I save photos, their local copies are deleted almost immediately. This means that the media browser (UIImagePickerController) does not show these photos. On my iPad, the only photos shown are two screenshots I took on my phone last August.
Also, on my iPad, Photos shows as taking up 1.0 GB, while the same library takes up 7.0GB on my phone. Both devices are 32GB devices with 2+ GB of free space, but this issue is only present on my iPad.
