Had the logic board replaced in my iMac and its doing some odd things now. First it wouldn't let me play songs I had downloaded saying that I wasn't signed into Apple Music when I was. Found a fix online that had me remove a cache folder in iTunes. Now I can't download any songs. They show up in my library, but as soon as I click the cloud icon, I just get the circle. Its pausing the download and refuses to resume no matter what I do. Any ideas?
