Hi there Nef704, we came across your post and wanted to offer some assistance.
We completely understand that this is not an ideal situation. Not to worry though, we'll do our best to get this sorted for you.
Unfortunately, we cannot change the date of birth from our side. However, you can amend this via the Accounts Center.
Alternatively, it might be best to look into app sharing. This is where the device owner can share eligible apps and games with additional profiles on the headset. For more information on this, please head over to our website.
If you have any other questions or queries, please don't hesitate to send us a PM. To do this, please go to our profile or click here.
Hope to see you in the Metaverse soon!
