ios devices do not show all matched songs
Several days ago I accidentally unselected iTunes Match on my iMac's main library. After I rebuilt my iTunes Match library, hundreds of songs showing "Matched" do not show as available on my iOS devices (iOS 6.0.1).
In some cases, one song from an album may be available on the iOS devices the other "Matched" songs are greyed out and cannot be downloaded to the device.
This continues several days later.
