Can't change my birth date and region

[Lexiosity]

So, I logged into my Pretendo Network ID, and of course, since the NNID app still uses the initial functionality, we cant change our birth date and region, and we're unable to set it on the website, so if possible, we should be able to sort these options out on the website, since it won't be possible on 3DS.

Also, we can't verify our emails via the app because we get a vanilla nintendo error when trying to resend confirmation email.
