Q: To hide or restore purchases on an iOS device is not working
It doesn't work on iOS 6, and I don't know if it's permanent or only temporary. You should still be able to hide and unhide things via your computer's iTunes, and you can still view and download hidden items on iOS 6 (but not hide or unhide them).
