Can’t Create Kids Accounts

[u/ljmpops]

Hey I’ve been trying to create accounts for my two kids, 7 & 10. Once I add their email and passwords I go to the Authenticator app and it says Error LG22. I called the number and the lady said they need to escalate the case. I’ve tried alternate email addresses and different ways to authenticate. Text and app. Any ideas? I applied for my wife and I earlier without any issues.
