I had a similar problem in the first 2 days after IOS 7 was released. iTunes Match would not update, and previously matched tunes showed "waiting". After many attempts to resolve the problem... Re authorizing my computer, numerous forced updates iTunes Match... the problem has resolved itself. As of Sept. 22, all functions have returned to normal. Playlists and artwork for 110G working, and access able from all my devices.
