Hello Apple,
I think it is wonderful that you are the most valuable company in the world. That you're building a self-driving car. That your products are as beautiful as they are well built.
But this, this is ridiculous. Your company was founded on the end user and their content. Music, Movies, TV Shows, Books. This very basic problem we're all facing, most of us on your latest hardware and software, is simply put unacceptable.
We use your latest iBooks on the latest OS X, with the latest iOS on your latest iPad and iPhone.
We have a huge collection of ePubs, that show up in iTunes under Audiobooks. If it weren't for google and a lot of research, I would have never guessed that my disappeared books are actually under Audiobooks in iTunes. And every time I want to sync an iOS device with iTunes, I need to go into the Audiobooks section, select the epub, Get Info, and go on to the next until they are all put back in the Books database of syncing.
I mean really?
This thread dates back more than a month.
There have been around 2 new updates of iTunes since then and no fixes.
Who manages your quality control?
This was a problem that didn't exist before and NOW exists. It is not a new product that comes with inherent bugs and quirks to iron out.
As much as I respect your one year cycle of new iOS and OS X products. It does seem to me that this is one of many examples of things that weren't broke that became broke, and that you're either stretched thin in terms of human resources or your quality control systems are failing you.
I am deeply frustrated, because this is not the first of many user-unfriendly bugs that anyone with slightly less tech savvy would never figure out.
A loyal customer and fan,
Nick
