It’s a Bug, iOS 15 users encounter problems when loading the app. Apple Music The app will replace the old music apps like Spotify if users keep it in the dock, Apple says it’s a bug that’s working on fixing.
Problem loading the Apple Music app will overwrite the original music app on the dock.
Several iOS users on Twitter have reported issues loading the Apple Music app in the App Store, and the app replaces the original music app stored in the dock.
For example, if we drag the Spotify app to the Dock and load the Apple Music app from the App Store, the Apple Music app will immediately replace the Spotify app on the Dock.
Seems like if you download the Apple Music app from App Store, it will automatically appear on your device (iPhone) dock, more than this, it will change any other 3d party app with the Music app. If on your dock, you only have Apple apps it won’t do anything. pic.twitter.com/c0pkO9G2pq

The bug has led users to understand whether Apple is trying to promote the Apple Music app too much, its own music service, but MacRumors has confirmed that it’s a bug in the system.
(This issue happened with iOS 15.4.1, and it happened in 2019, and of course someone digs the issue and teases Apple again.)
