Hi,

Thank you for contacting Mobile Ads SDK Support team.

It is always recommended to use the latest version of the SDKs and the Unity Editor Version. As of today, the latest version of the Unity Editor Version is 6000.2.8f1 and the Google Mobile Ads Unity Plugin v10.5.0 and Unity Ads Mediation Plugin is 4.16.3.0 .

Could you confirm whether you have followed all the steps to integrate the Unity Ads with Mediation?

Please note that if you don't see your third-party ad source listed in the Adapter tab, this could mean you haven't added the ad source in your AdMob account. Learn how to set up a waterfall ad source and a bidding ad source. Once you've set up the ad source correctly, make sure you've added it to a mediation group.

Didn't initialize means Each third-party ad source SDK adapter needs to be explicitly initialized in your codebase with the necessary parameters. 

Kindly provide the below information via reply to author option for further investigation: 

• app ID
• ad unit ID

Thanks,
 

Mobile Ads SDK Team
