In an effort to provide the most effective tools for profitable ad campaigns, Category Targeting is no longer available for Pops campaigns. If you've added Category Targets to any of your campaigns, they are now marked "Disabled" in the Approval column on your campaign's Targets tab and will no longer receive traffic. Data from your Category Targets will remain available in Reporting and on the Targets tab. You may archive these targets to hide them from the default view on the Targets tab.
