Hi! If you're here, that means you've successfully setup ad optimization, and now you're looking to change the settings.
You can update the settings for campaigns already uploaded to Ad Optimization in the home screen.
Navigate to the section that says "the following campaigns have ad optimization". This will list the campaigns with ad optimization configured.
Here, you can change the number of active ads running and change the status of the ad. Just make the updates in each row and click 'Update'.
