Facing error when updating child's DOB on Apple Account
My husband set up Apple ID’s for my sons a few years ago so they could save their game progress on our iPads by signing into their own accounts. Fast forward a few years and they have just got mobile phones so are now using the same Apple accounts to log in (linked to their Gmail accounts which I set up when they were born). Turns out my husband used any old date for a birthday when setting up their Apple accounts all those years ago so they are now 10 and 15 in their respective profiles which means they have completely different content restrictions, neither of which are correct for them as they are actually 13! I have tried changing from within each of their accounts which triggers an email to myself containing a link to log into my own Apple account and verify the change of date. Except every time I try to authorise it, it says there is a server error. I have tried from my iPhone, iPad, Mac and PC to no avail! Any suggestions as to where I’m going wrong please?
