Its saying certify Apple Cash but I’m not 18 so I cant

If you're under 18 and unable to verify your Apple Cash account because you don't have a Social Security Number (SSN), there are a few steps you can take:

Depending on your country or region, you may be able to set up an Apple Cash Family account with the consent of a parent or legal guardian. This would allow them to manage and oversee your Apple Cash transactions.

If none of the above options work and you're not in a hurry to use Apple Cash, you can simply wait until you turn 18 and can then set up and verify your account independently.

My son is 17 and when I try to setup Apple Cash in Family Sharing, it says it can’t be setup because he already has an Apple Cash account enabled. He believes it’s an account he created and lied about his age. How can I locate and delete that account so that we can setup Apple Cash?
