When a family member tries to join a session via scanning the barcode, it receives: "This function not available for your account". What are possible reasons ?

Hi dancearmada,

The requirements for the feature you describe are covered in the related article titled Play music together in a car with SharePlay and Apple Music. Double-check that link to ensure you've covered the following:

"Here's what you need

To host a SharePlay session in the car, you need:

• A subscription to Apple Music
• An iPhone updated to the latest version of iOS

To join a SharePlay session in the car, you need:

• A passenger with an Apple Music subscription hosting a SharePlay session in the car
• An iPhone updated to the latest version of iOS
• Bluetooth turned on for your iPhone"

Ensure that the passenger meets those requirements, has Bluetooth enabled and not restricted.

Note the following from that article if the option is not presented:

"If you didn't get a notification to join a SharePlay session in the car

• Check that Music notifications are turned on: On your iPhone, go to Settings > Notifications > Music and turn on Allow Notifications.
• Make sure that Do Not Disturb is turned off on your iPhone: Swipe down from the upper-right corner of your screen to open Control Center. Then tap Focus."

Confirm no restrictions on the affected device would prevent those notifications and that Focus is not enabled.

Regards.

Doesn’t work with some Apple IDs.

It always say "not available for you account". In my case is a children Apple ID.
