Hey Samuele13,
Thanks for taking the time to try those steps and for getting back to us with those details. I'd recommend trying these steps next:
- Tap Settings > iTunes & App Store > Apple ID > Sign Out.
- Restart your iPhone.
- Verify you're connected to a strong Wi-Fi or cellular network.
- Tap Settings > iTunes & App Store > Sign In.
- Open the Music app and take some time to test for the behavior.
If the prompt continues, use these steps to remove the Music app from your device and download it again. This will also remove any downloaded content within the Music app and can be redownloaded after the app is reinstalled:
- On your iOS or iPadOS device, touch and hold the app.
- Tap Rearrange Apps.
- Tap in the upper-left corner to delete the app.
- Tap Delete. Then on an iPhone X or later, tap Done. Or on an iPhone 8 or earlier, press the Home button.
If you have an Apple Watch, deleting an app from your iPhone also deletes that app from your Apple Watch.
- On your iOS or iPadOS device, go to the App Store.
- Search for the app. Make sure that you use the exact name of the app. Find the correct name of built-in apps.
- Tap to restore the app.
- Wait for the app to restore, then open it from your Home screen.
If you have an Apple Watch, restoring an app to your iPhone also restores that app to your Apple Watch."
Delete built-in Apple apps on your iOS 12, iOS 13, or iPadOS device or Apple Watch
Let me know what you find.
Best Regards.
