ember cli simple auth devise last version 0.8.0-beta.1

I am trying to set up ember cli simple auth devise in my app, actually I found many examples and similar issues but still not able to solve a problem that I am fighting many hours, it is the last version of the addon 0.8.0-beta.1, the authentication works perfect but when I try to visit a page under a token authorization, the token is not sending in the header:

The thing I am thinking which causes this is the devise authorization in the config file, I have it the same described in the doc:

ENV['simple-auth'] = {
    authorizer: 'simple-auth-authorizer:devise'
}

I have the whole code in this repo, if you could give a feedback it will be really appreciated!!!
