Q: I don't have the "make available offline" option anymore , any help?! Please!

Hello YungJ,

Thanks for using Apple Support Communities.

I see from your post that you're unable to make songs available offline from Apple Music.  First and foremost please ensure you have Apple Music and iCloud Music enabled:

Turn on iCloud Music Library

With your Apple Music membership, you can sync your music by turning on iCloud Music Library on all of the devices on which you want to use Apple Music.

On your iPhone, iPad, or iPod touch

1. In the Apple Music app, tap the profile icon and sign in with the same Apple ID and password that you use for your Apple Music membership. 
2. From your device's Home screen, go to Settings > Music, and turn on iCloud Music Library.
   
3. If you already have music on your device, you'll be asked if you want to Merge or Replace the music. Choose Merge to add the songs currently on your device to your library.* If you select Replace, the music on your device is replaced with your Apple Music library.

Sync Apple Music across your iPhone, iPad, iPod touch and computer

Take care.
