1. As per your screenshot of Ad Data there are many requests, but match rate is very low. Generally it is around 90-100%.

2. Check your implementation and update as per best practices given by google. Important in Ad is : Control on Ad request.

3. Check all user path, and do request accordingly, Use Analytics, Events to check how user is using your app and after request ad , is it presenting or not

4. change placement of ad according to the data of analytics
