Hi,
Upon checking your account with the provided information, we found an “Ad serving is limited” issue in the policy center, which must be resolved. It is currently limited because of invalid traffic concerns.
It seems that you may have accidentally clicked on your test ads without adding your test device either manually or programmatically. This could be one reason for the issue you’re experiencing. For more information, please refer to the documentation on enabling test ads for Android and iOS.
What you can do:
