Maybe I am mistaken in what this plugin provides. However, I am under the impression that like the 'jetpack' wp.me shortlink generator WP Bit.ly replaced the shortlink with your Bit.ly account. Therefore, I have installed WP Bit.ly and deactivated jetpack's wp.me. But the button when creating/editing a post that says 'get shortlink' is now gone and I see no other evidence of this plugin. What is the issue here?
