Unable to set up Child account because of error "Invalid Phone Number"
Hello:
"Santa Clause" brought an iPad Gen 9 to my kid. I am trying to create a kid's apple app store account using the path in my iphone: "Settings > "Family Sharing" > "Invite Family Create Child Account" . After I put every detail as it is, date of birth, confirm that I'm an adult buy setting up my Debit/credit Card, and go through the painful long process, I get an error message "Your Phone Number is Invalid" I hace tried my correct phone number, and also my wife's phone number and I cannot get thos resolved. Is Super frustrating. Can I get help for this please?
iPhone 11, iOS 15
