Apple Music Profile not visible on iPhone.

Hello reshukr,

You should be able to turn on the Sync Library option using the steps below:

1. Make sure that your iPhone or iPad is signed in with the same Apple ID that you use with your Apple Music subscription.

2. Go to Settings.

3. Tap Music.

4. Turn on Sync Library.

5. Turn on Sync Library on your other devices.

You can also find those steps in this resource: Use Sync Library to access your music library across your devices - Apple Support

If you aren't seeing that option, or if that behavior persists while Sync Library is enabled, let's use the steps below to get your iPhone updated to the latest iOS: Update your iPhone or iPad - Apple Support

1. Back up your device using iCloud or your computer.

2. Plug your device into power and connect to the internet with Wi-Fi.

3. Go to Settings > General, then tap Software Update.

4. If you see more than one software update option available, choose the one that you want to install.

5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do.

Updating should help to further isolate any software conflicts.

Let us know your results, and we'll keep moving forward from there.
