I've recently subscribed to iTune Match with my MacBook Pro (OS 10.9), but can't seem to get my IOS (7.1) devices to acknowlege that subscription. Apple's troubleshooting website offers a screen shot of "settings" -> Music -> turn on iTune Match which doesn't have the same appearance to my IOS 7.1 screens (iPad 2; iPhone 5c). All that is visible is to "subscribe to iTunes Match" which has already been done. iTunes Radio still has the ads, etc. which is supposed to be disabled with iTune Match subscription. All devices use the same Apple ID.
