Creating child account

When trying to create a child’s account, I click ‘Verify You’re an Adult’ and it takes me to the Parental Consent screen where it asks me to enter the verification code that was texted to me in order to use PayPal. After entering the code, I either get an error saying ‘There was an error, please try later’ or it says ‘Credit card processing is temporarily unavailable…’ I’ve been trying for a few days and I keep getting the same errors. I’ve tried creating the account on the old iPhone that my son will be using and also from my current iPhone by going under settings then family. I’ve tried over Wi-Fi and I’ve also turned the Wi-Fi off and tried over data. Any suggestions?
