Why can’t we turn on family sharing.

Hello nyah2008,

We have a great support article that might help with this. Start out by following the steps in this article to make sure Family Sharing is being configured properly and all devices involved are eligible to use it: Set up Family Sharing - Apple Support. Follow these steps:

"Start a family group

One adult in the family — the family organizer — can set up Family Sharing for the group from their iPhone, iPad, iPod touch, or Mac. If purchase sharing is turned on, the family organizer pays for family members' purchases and must have a valid payment method on file.3 

On your iPhone, iPad, or iPod touch

1. Go to Settings.
2. Tap your name.
3. Tap Family Sharing, then tap Set Up Your Family.
4. 
5. 
   
6. Follow the onscreen instructions to set up your family and invite your family members.
