Hi Jking150,
For help with the Ask To Buy feature not working as expected, test the steps below found in the article here: If Ask to Buy isn't working - Apple Support
"Review your Family Sharing settings
If you're the family organizer, you can go to your Settings or System Preferences to see if your family members' accounts have Ask to Buy turned on.
On your iPhone, iPad, or iPod touch
- Go to Settings.
- Tap Family. If you don't see Family, tap your name, then tap Family Sharing.
- If you're the family organizer, make sure that Purchase Sharing is turned on. Then you can tap a family member's name to see if Ask to Buy is turned on for their account."
There's additional information and settings to check in the article. If the issue continues, reach out to Apple Support directly to further assist.
