Adding a child to Apple Wallet
I am trying to set up my child to receive Apple Cash and it is saying it is unavailable both phones have been updated so I am not sure what the issue is.
iPhone 16 Plus
What device model and IOS are they using? Are you the family organizer? If so, again, what device and iOS version?
Are you following the instructions in the Apple Support article I linked below? If so, are you receiving any error messages and if so, exactly what does it say?
