Since I have had my 5s, when I connected to iTunes it would show my custom ringtones and alerts in a "tones" tab, which was there with the movies, music, etc. But now, and this may have happened since the last iTunes update but I'm not sure, it does not show a "tones" tab or category at all. If I do a backup to the computer, and then restore from that backup, the tones will not be re-installed onto my phone. But if I do an iCloud backup, and then restore from it, the tones are reinstalled. Any ideas on what is going on?
