Although my voice memos app shows no memos, when I connect my iPhone to my Mac and browse to
On This iPhone > Voice Memos in iTunes, every voice memo I’ve recorded for the last three years is there (even ones recorded on my previous iPhone).
I tried removing my entire music collection from my iPhone, but they survived. How do I delete them?
Update: Whatever this bug was, it doesn't seem to be present any longer with iOS 8.
