iTunes Match - lots missing on new laptop
Just subscribed to iTunes Match for new HP Stream laptop with very small storage capacity. After turning on Match and authorising the new laptop, my library is there in full but it won't let me play most of it. Sometimes it lets me play something, but mostly when I try a popup says "all downloads and file copies have been paused - the disk you're attempting to use is full".
I know the disk would be full if it tried to download everything but I thought the whole point is to stream the music, not download it? Wireless is on and working.
Any ideas? Thanks.
