Long-running support case: incorrect DOB prevents parental supervision

My minor son's Meta/Quest account was accidentally created with a parent's adult date of birth. The account has substantial purchase history, game progress, and other history, so simply abandoning it and creating a new account would mean losing quite a bit.

The central problem is straightforward: because the account still shows an adult DOB, Meta Family Center will not allow me to supervise the account. We have already gone through Meta's requested age/identity verification process, but the DOB remains unchanged. Attempts to correct it through Accounts Center lead to a circular message telling us to use Accounts Center on a desktop/laptop—even when we are already doing exactly that.

Meta Store Support has kept our case open and sends regular emails saying the issue is still being investigated, which I appreciate. However, after several months there has been no substantive progress or indication that the account has reached a team capable of correcting the DOB/account age state.

The goal is simply to preserve the established account while allowing a parent to properly supervise a minor's Quest account.
