After installing , some users found that their iTunes Match Music icon had vanished from the main menu. In most cases, the fix is simple.

The basis for the fix derives from a new feature in 5.1, a feature not mentioned in the . An explains that you can now hide selected icons from the main menu display. To do so, go to Settings -> General -> Parental Controls and select to Show or Hide each listed item.

An suggests that a bug in this feature may be behind the missing Music icon. To get the icon to return, go to the Parental Controls and locate the iTunes Match item. It will probably be listed as "Show." Even though "Show" is the desired setting, select "Hide." Wait a moment and then select "Show" again. When you return to the main menu, the Music icon should now be visible.

Oddly, in my testing, I had almost the opposite problem. The Music icon remains visible and active regardless of the setting I select for iTunes Match in Parental Controls. The settings work as expected for other items in the list.
