Shared Photo Streams in Usage, despite sharing turned off.
I checked the usage on my iPad today (running iOS 8.1) and Shared Photo Streams are using 4.1GB of memory. The problem is that I don't have any shared photo streams -- I don't even have sharing services turned on.
I've tried Googling, but I can't come up with any solution to this.
