Recover Account - Usless Button and UI/UX?

[SPIRY-RO]

I have saved only the details that are useful for NEX UI/UX nothing extra necessary that would expose my account security unnecessary since my password and username are in my brain.

Decided that as UI/UX exposed only the Private Key Backup Code + Username + Password, are the only necessities to recover the access back into NEX application.

But it fails to do anything. At first I tough is the password, but it gives an error as "account recovery info is invalid". When I but the correct info, I am sent into a circle of death loop. Waiting to recover my account based on the requested info yet failed..

I have done all necessary from reinstalling the application, Chrome, Resetting data... yet no success.
