I have set up a couple of Ad Schedules on some campaigns and I am using the CampaignCriterionService to obtain them. I pass the AD_SCHEDULE string to the Selector, however when I iterate over $page->getEntries() which is a CampaignCriterion[] and invoking the getCriterion() function it just returns the base type not an AdSchedule, which I need to get the star and end times.
Any help is much appreciated.
