Rest assured that nothing is wrong with your iphone, ipod touch, or ipad. It's the idiotic IOS updates that are taking away features like grouping music videos by artist, chapter titles, audio titles (for multiple audio streams), and even displaying song lyrics on the new ipad 3. When my audio titles started to disappear (around 3 IOS updates ago), I posted it on the feedback site and called Apple technical support. The technical support people I talked to were totally ignorant and useless. And, obviously, if Apple cared and took the time to read and act on the posts on their feedback site, they would have been aware of the issue and taken steps to restore audio titles and insure chapter titles didn't disappear too like they did in the last update(5.1).
Does anyone have experience with android devices? Is this OS maintained better? Does it have the features we're losing with Apple?
