Can’t sign in. – Mixer Create Review

Doesn’t allow me to sign in, every time I click on the ‘Create New Account’ button, it comes up with ‘Response status code: 400’ by the way I am trying this on an iPod 6th gen. I’m curious to know if I don’t have a compatible device, or maybe the iPod is too old to handle it.
