As somebody who has zero interest in subscribing to Apple Music I have enjoyed the iOS Music app setting to hide Apple Music. So I read with great surprise that apparently that setting has disappeared in the latest iOS 14 beta.
A couple options.
Hiding it will be the default in iOS 14 and Apple Music only appears in the Music app for those who have already bought it.
Apple Music will always be displayed in the Music app. Those who already buy it want it there and those who haven’t yet subscribed shall be forcefully reminded they absolutely need it. Services!
This is just an issue in this particular beta. The toggle will be back in the shipping release version of iOS 14.
