Changing the Campaign End Date

The only thing you need to do to extend the run-time of a finished campaign is open the campaign, adjust your budget accordingly, and change the end time.

If your campaign has already ended and you decide to change the end date, you need to make sure you synchronise your campaign afterwards. The reason for this is that, when a campaign is active, it's regularly synchronised with Facebook. However, when it's paused or finished, we stop these checks. That's why changing the end date after it ends causes this synchronisation problem.
