iTunes not showing recently bought music
So today I logged in to iTunes, and saw that the music I've bought most recently is not showing. The songs that I bought months ago aren't there, songs that I bought a week ago, an album that I bought back in May, but for some reason the album that I just bought the other day is showing. I almost always buy my music off my phone, and I hardly ever use iTunes, maybe that's part of the reason why? But I really need to fix this because I bought a new laptop and need to transfer my library. Is there a way to fix this?
