I am using AdMob ad mediation and have configured other ad networks such as Mintergral and AppLovin. I have correctly installed/imported the mediation adapters into the application. However, only AdMob is working fine, and all other ad networks are failing. There are no displayed adapters in the Adapters section.
1. I have checked the AdMob console and verified the configurations of other ad networks, but I couldn't find any issues.
2. We have tested using the Ad Inspector and Test Suite:
- Ad Inspector shows information only for AdMob and no other third-party ad sources.
- Test Suite shows that AdMob can request and display ads normally, but the third-party ad sources have ad configurations, and adapter information is correct. However, the initialization of the third-party ad source adapters failed.
3. As an experiment, I used my friend's AdMob account (Account B) with a well-monetized product (Product Y) having a different package name. I changed my problematic product's (Product X) package name to that of Product Y while keeping the rest of the code unchanged. By using Account B's AdMob ID for Product Y, all the ad networks worked normally.
- Then, I changed Product Y's package name to that of Product X while keeping the rest of the code unchanged. This time, using Account A's AdMob ID for Product X, all the ad networks, except AdMob, failed to initialize the SDK and request ads.
Based on these observations, I suspect that my AdMob account (Account A) might be subject to certain restrictions.
