Hello Guys, Need some help with issue with amount of impresions. I have: Remnant CPM campaign with no limits of impressions; One site - no restrictions; Three banners - no restrictions; Three zones (Asynchronous JS Tag)- no restrictions; The site has about 4k visits per day with 5 page views each. It means that site should have about 60k of impressions. But I see only 12к of impressions. I'm an impasse because there are no restrictions. There is no problem with servers. When I use banners directly (without AdServer) I see 60k of impression but I have to use AdServer. Did anyone has the same experience and know how to solve this problem?
