I have made the necessary settings in the buildbox interface. Ads still do not appear. Can you help test ads?
If Ads are not showing it means your video ad id area is empty you must enter video ad id even if you are not using reward video and make sure do not use your own ads for testing. your account will be suspend use test ads unit provided by google ads if your test ads are working it means your real ads will defiantly work. test ads link below https://developers.google.com/admob/android/test-ads
