I know it isn't available to the public yet, but I have a dev account. iTunes match worked fine a month ago although it matched maybe 2% of my music. Now, when I initially turn on iTunes Match, the progress bars appear frozen on my mac but after 10 minutes or so it says everything was successful and my library is available on all my devices. However, when I turn on itunes match on my iOS devices, there are no songs available. Anyone else having this issue??
