Google Ads stop to work


I created a game on android that contains ads admobs. These ads worked for 1 week and generated 3 € but they stopped working when I added a way to load an ad for second chance tokkens.

So I deleted that even if I did not understand why it did not work anymore and it does not change. The ads do not come back.

There is my settings :

“Menu” level (loaded by the same way in main level)

And called in the widget :

UP; please someone can help me ?
