PIN-based authorization and 2 steps verification process error

[perecedero]

My App use PIN-based authorization (https://dev.twitter.com/docs/auth/pin-based-authorization), and the users are forced to sign-in in twitter to can get the Pin page.

So the flow must be:

My App => Twitter Sign-in page --> Twitter pin page 

With 2 step verification process, the flow should change but only on twitter side

My App => Twitter Sign-in page -->  Twitter enter code page --> Twitter pin page 

But that is not happening, Users never receive the code or the code page.

I missing something?
