Hello Nino Linden,
Welcome to Microsoft Q&A forum.
Before we proceed, please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas. To make sure, I'd like to know if your account is ever being in a Family group before, and if you have ever changed the birthdate of the account?
I'm waiting for your reply.
