Apple Music
I cannot see album covers on apple music and it will not let me download music either. I have tried turning icloud music on and off and nothing seems to work.
iPhone 6 Plus, iOS 12
If you can't download, play, or access songs
First, check iTunes to see if the song is ineligible for upload. Additionally, if you added the song to your library from the Apple Music catalog, it might no longer be available on Apple Music.
Check your Internet connection
Open Safari on your iOS device or Mac, or a web browser on your PC, and go to any website to make sure that you have a strong Wi-Fi or Internet connection.
If you can't connect to a Wi-Fi network on your iOS device, you can try using cellular data:
- Go to Settings > [your name] > iTunes & App Store.
- Turn on Use Cellular Data.
You might have to pay a fee to download over a cellular network. Contact your wireless carrier for details, and learn about cellular data settings and usage.
