Why is my EA account asking me for proof of my age?

I live in Mexico. We don't have any laws that require us to disclose our age to access these materials. So why is the app asking me for this all of a sudden?

I clicked on the "Learn More" link and it leads to https://help.ea.com/en/articles/ea-account/age-assurance/ - a page that does not exist.

There's this link in the app too, but clicking it does nothing. I searched the help pages, found nothing that referred to this requirement. So what the heck is going on?
