I’m not receiving the notifications to approve or decline app downloads

Hi grady264,

Thanks for connecting with us here in Apple Support Communities. You've reached us from a great article son how to set up Ask to Buy on your son's device. Were you able to follow all those steps listed here? See: Approve what kids buy with Ask to Buy

If so, and if it's still not working you'll want to check out this article as it may address the issue you're facing: If Ask to Buy isn't working

If your Ask to Buy requests are missing

If you miss an Ask to Buy notification, you can find the request in Notification Center on your iPhone, iPad, iPod touch, or Mac. If you still don't see your Ask to Buy requests, check your Family Sharing settings, check which Apple ID you're signed in with, and make sure that you're on a supported device.

Open Notification Center on your iPhone, iPad, or iPod touch

From the Lock Screen, swipe up from the middle of the screen.

From any other screen, swipe down from the center of the top of your screen.

Open Notification Center on your Mac

Click the date in the upper right corner of your screen or swipe left with two fingers from the right edge of your trackpad. Notifications show up at the top of Notification Center.

Cheers.
