While using Admob, Test mode is working perfectly. But with ad units, ads are not loading with error code 401 and 102 for banner ads and interstitial ads also fails with the message cannot load ads with error code 201 sometimes. I have checked ad units many times its correct and implemented ads according to admob policy. Checked with android studio with same ad units its working. So, guys urs views and opinion is required. What’s going wrong.
