iTunes purchases are not downloading
I just made some purchases in the iTunes store (several TV series). I left the PC for a little while to give them time to start downloading, but when I came back about an hour later, there is no sign of them in my library.
I tried "check for available downloads" but that reported "no downloads available", as it always does.
I went back to the store to make sure the purchases had gone through. The TV series said "purchased". There is a cloud icon next to each episode, so I guess that is how I can download them. But is this really the way we're supposed to download purchases - manually, one episode at a time? Isn't there some way to download the whole season that I've bought?
Finally, since "check for available downloads" never finds any available downloads, what is it for?
