I am attempting to integrate Admob Mediation with Unity Ads, what I mean is I would like the Admob Unity SDK to drive the mediation and decide if it should display the Admob or Unity Ad based on highest revenue. As my starting point I am using this tutorial https://developers.google.com/admob/unity/mediation/unity Although it is out of date I was able to account for the differences in the dashboard and complete all the steps. On the Unity Side was unable to simply turn on the Unity Ads service as this gave me errors. After some email exchanges with Unity Support I was told that instead I had to import the package from the Unity Asset Store which I did. My understanding is that as long as the Admob SDK is in my Unity Project along the side of the Unity Ads SDK and the Mediation is setup correctly on the Admob Dashboard then the Admob SDK should be able to correctly choose the best paying ad and display it. Although I am calling the Admob SDK code as usual I am not making any calls or initiations to the Unity SDK (I am not sure that is correct) However in reality all I ever get are Admob Ads with 0 Unity Ads impressions even after several weeks of running. I should ad that I am not using Rewarded Ads just Interstitial ads. I tried contacting Unity Support about this but it has now been 1 week since I received a reply (despite several emails asking for more help). Because I see the Network Request coming through the mediation window in Admob & Unity Ads I feel like I am close but I must me missing something because I never get any impressions. I am using Unity 2017.3.1f1 Any ideas?
