Well, after a weekend of complete disaster and nightmares for iTunes Match, everything is back to normal except one major flaw that's really annoying me.
On friday no other tracks but the matched ones would stream on either my Apple TV or my secondary computer. They wouldn't download if I wanted them to on this secondary computer. Music videos included.
Later last evening every track on iCloud started working properly again. Except music videos. They'd not download on my secondary computer. They wouldn't stream on my Apple TV. I did some tests and out of 208 music videos currently compatible with iCloud (because they were purchased with the same account) only 3 actually stream and download. So either this is part of the temporary breakdown iTunes Match has been suffering, or because of it my music videos are corrupted.
I've contacted Customer Support 4 times to no avail so far regarding a response. Either I can play/download my music videos again or one of the main features for me of iTunes Match on my Apple TV is absolutely broken and useless.
Apple really needs to address this and solve my problem. Otherwise iTunes Match is only partially working. What would the use of buying music videos at the iTunes Store would be for me from now on???
