I've been on Apple Music pretty much since the start and even though there have been bumps along the way it's solid now and with the iOS 10 UI improvements it's a much better app to use.
One area that I like to keep an eye on is the progress of my downloading music, here is how to do it
- Tap MUSIC
- Select an album and tap the Cloud icon to download
- Navigate back to the library by double tapping Library
- Tap Downloaded Music
- You will see a new option called Downloading, tap this and you will the status of everything currently downloading.
