I cant use apple sing

Good day to you mariaing, 

Looks like you came from a great article on the use of Apple Music Sing - See lyrics and sing in Apple Music on your iPhone or iPad

After viewing the lyrics, is the Mic button visible or is it missing? If it is visible, when you tap it do you see an error or does just nothing happen? 

If you don't see the Mic button

Apple Music Sing is supported on the following iPhone and iPad models:

• iPhone 11 and later or iPhone SE (3rd generation) updated to the latest version of iOS

• iPad Pro (5th generation and later), iPad Air (4th generation and later), iPad mini (6th generation), or iPad (9th generation and later) updated to the latest version of iPadOS 

Not sure which iPad model you have?

If you want to AirPlay to HomePod, first tap the Mic button on your iPhone or iPad.

If you're using a supported iPhone or iPad and don't see the Mic button, Apple Music Sing might not be available for that song.

Also, if you haven’t already, be sure to - 

• Quit and relaunch the Music app and try again Close an app on your iPhone or iPod touch

• Restart your iPhone and try again Restart your iPhone

• Make sure your iPhone is up to date with iOS 16.3 Update your iPhone or iPad

Thanks.
