I can't figure out how to solve this. GDrive says I'm out of space - WAY OUT OF SPACE. As in, 44.6GB out of 15GB used. This can only be because I had a ~40GB iPhoto Library that got backed up because it happened about a day after that backup started. My understanding was that those photos would not count towards my quota, but regardless I went ahead and deleted it, and all the photos it had backed up from my phone, and yes I emptied the trash days ago. But it still says I'm completely, massively out of space.
How can I get back to under 15GB as I was before this?
