Hi Krasimir,

 

Thank you for reaching out to us.

 

It seems that you've incorrectly entered an ad unit ID instead of an app ID in the AdMob settings of your Unity project. Kindly note that app IDs have a tilde (~) in the middle; ad unit IDs, on the other hand, have a forward slash (/) instead. With this in mind, you may try using the sample app ID from the first link above to see if it would fix the issue.

Hi Shota,

Thank you for reaching out to us.

As the error mentioned, this is the error when you mistakenly used an invalid app id. An example of an app id is like "ca-app-pub-3940256099942544~3347511713" while the ad unit id is ca-app-pub-3940256099942544/6300978111. You can follow this guide on how you can set up your AdMob App ID. Also, you can check this article on where you can find your app Id in your account.

On the other hand, I've deleted your post as it contains private information.
