title: Mailto in ReactNative
body: <p>I try to add a button to send an email from the mail provider of the user, like so</p>
  
  <pre><code>_OnPressMailto(emails){
    console.log(emails[0].email)
    const address = emails[0].email
    Linking.openURL('mailto:address');
  }
  </code></pre>
  
  <p><code>Linking.openURL</code> works perfectly for my other links to fb and twitter. But the mailto returns an error=> Unhandled Promise. </p>
  
  <p>An idea ?</p>
