How do I delete a Playlist Folder in Apple Music on iOS?

Thanks for trying that and getting back to us, Fixar Frazze. It’s appreciated.

Let see if signing out of your Apple ID removes the folder. Go to Settings > [your name] > Media & Purchases. Tap Sign Out, provide your Apple ID password if needed and complete the process. Once you’re signed out, Restart your iPhone. Once your iPhone is back to the Home screen, return to Settings > [your name] > Media & Purchases and sign in again.

Once you’re signed in, check the Music app and see if the folder’s been removed.

If not, we recommend reaching out to Apple Support to look into this issue further with you: Get Support

All the best.

Greetings Fixar Frazze,

Welcome to Apple Support Communities. You can delete the old playlist folders from the Music app on the Mac. Open the Music app, and open an old playlist. Click the three dots to the right and click "Delete From Library". Once you've done that will all of the old playlists, sync the iPhone to the Mac using the Apple Support article guidance: Use iTunes to sync your iPhone, iPad, or iPod with your computer - Apple Support

"Sync or remove content using iTunes

1. Open iTunes and connect your device to your computer with a USB cable.
2. Click the device icon in the upper-left corner of the iTunes window. Learn what to do if you don't see the icon. 
3. From the list under Settings on the left side of the iTunes window, click the type of content that you want to sync or remove.* To turn syncing on for a content type, select the checkbox next to Sync.
4. Select the checkbox next to each item that you want to sync.
5. Click the Apply button in the lower-right corner of the window. If syncing doesn't start automatically, click the Sync button."

Let us know the outcome, and we can go from there if needed.

Best regards!
