Hey, i have two advertisers with the same settings, same campaign and same settings for the banners. Now when i want to show one banner of advertiser A on my wide skyscraper and at the same time one banner of advertiser B on my leaderboard, the banner of advertiser A gets delivered but not the banner of advertiser B. I set the cache to 0 to see instant changes, but nothing happens. When i deactivate advertiser A's banner, the other one then gets delivered. Putting advertiser B's banner to the banner-collection of advertiser A works fine, but thats not the approperiate way to handle this… Can someone help me out?
