New Post: Authentication - Twitter asks to authorize app every time.

Hello,

working in an app and after implementing succesfully the login, someone asked me why the app keeps asking me, when I redirect to twitter, that I should authorize the app again, if according to the documentation, Twitter should only ask the user once to authorize the app. From there, if you go again to that site, Twitter should only redirect you to the callback, but no ask you again to "re-authorize" the app.

Can you tell me if this is normal or not and why?
In case isn't normal, can you give me some assistance to fix it?

Thanks
