Hi,
Thank you for reaching out to us.
With regard to your concern, kindly note that the AdMob mediation is a feature that lets you serve ads to your apps from multiple sources, including the AdMob Network, third-party ad networks, and AdMob campaigns (https://support.google.com/admob/answer/6162747). AdMob mediation helps maximize your fill rate and increase your monetization by sending ad requests to multiple networks to ensure you find the best available network to serve ads. In addition to that, if your account was created using AdMob, you cannot connect it in a AdManager account, and they have different App ID and ad unit id format.
