Minor account stuck in consent loop

This usually happens if the child account was created in a different region, the date of birth was recently changed, or the consent process did not fully complete on the parent account. Please try the following:

1. Sign in to your parent account at Microsoft Family https://account.microsoft.com/family
2. Remove the child account from your family group.
3. Sign out of all Microsoft accounts in your browser, then clear cache or use InPrivate mode.
4. Add the child account again from your organizer account and complete the consent process when prompted.

Can you let me know if:

1. Is the child account set to the correct birth date?
2. Are both accounts registered in the same country or region?
3. Do you see any pending consent email in the parent account inbox?
