I should never have bought my daughter an iPad with only 32 GB of storage on it.
I never imagined she would use it as a camera and fill it with photos and videos. iCloud Photo Library has been enabled from the start, and we have plenty of cloud storage space. Unfortunately, Photos will not free up space no matter what I do. If you delete a photo or video from Photos, it is deleted everywhere, so that is not an option.
Tonight, as I update iOS via tethering the iPad to my Mac, I am weighing my next move. Do I wipe the iPad and set it up as new, which would at least forestall the problem? Or do I simply turn off iCloud sync, wait a while for the photos on the device to be deleted, and then turn it back on? I can’t remember if I have tried the latter before. I think I may wipe the device because my daughter’s notes app has 39 notes and is taking up over a gigabyte of space, too. Strange things are afoot.
