iTunes Match

So, having established that iTunes Match is not fit for consumption on my iPhone, I have expressly disabled it in settings. Apple has rather more confidence in how much I am going to like using iTunes Match so upon installing the 8.1.1 update Apple chooses to override the user preference and activate iTunes Match on the iPhone. Accordingly, all my playlists (that reference other playlists) disappear from my iPhone.

Recommendation: if you must be an iTunes Match user, and you have manually managed playlists that refer to eachother, only install iOS updates when you have enough time to manually disable Match and resync playlists after installing the update before you need to rely on the device behaving in line with user settings.
