Issue

Hi JaydeepKumar,

Thank you for contacting us.

Low match rate can be observed due to the following changes kindly refer them :

  1. Account changes
  2. Ad serving changes
  3. Usage changes

​​​​​​​I would recommend reaching out to the Product support team as they are better equipped to address your concern.Please note that we can only assist with technical queries/concerns related to the Mobile Ads SDK.

Solution

Just wait and be patient. It's just no proper Ads for you app.
