title: The App keeps asking for permission to "Have offline access", why?
body: <p>After having authorized the app with oAuth2 and acquiring permissions for requested scopes, I still get a screen asking if I grant the app permission to <strong>Have offline access</strong>, each time I try to login with Google oAuth2. Isn't it something that shouldn't appear again, once I grant it permission to have it?</p>
