For a while I monetized my application with admob and had not had any problems, these days I have been working on an update of my application but before launching it I have been testing and I have realized that now it does not show any publicity or nor interstitial banners being that I have not made any change in the code to upload ads.
If I install the previous version of my app (the one that is published) the ads are displayed correctly.
The following error is displayed:
