title: Heroku: ! You do not have access to the app heroku
body: <p>I originally had an app with the default name heroku set up. However I wanted to change this so I had two apps, an staging and production app. Following the heroku guide <a href="https://devcenter.heroku.com/articles/multiple-environments" rel="noreferrer">here</a> I think i've got it working, running <code>git remote -v</code> shows</p>
  
  <pre><code>heroku  git@heroku.com:oldapp.git (fetch)
  heroku  git@heroku.com:oldapp.git (push)
  staging git@heroku.com:newapp.git (fetch)
  staging git@heroku.com:newapp.git (push)
  </code></pre>
  
  <p>but I now want to change the name of heroku to "production". Running <code>heroku apps:rename production --app heroku</code> results in:</p>
  
  <pre><code>Renaming heroku to production... failed
   !    You do not have access to the app heroku.
  </code></pre>
  
  <p>Any ideas?</p>
