Ads doesnt work with new version ,anyone tried enhance extension?


Hi, there is no way i can get my ads working. Thw code is fine cause it work with test ad id, but no with my own id.
I thought it was api level but with the new offline actualization i have the same problem.

There is a site that offers to uploaf your apk and implement automatically code for ads, analitycs, etc.
It says it works with appybuilder

Have anyone tried it? What was your experience? I dont understand how i tell the page where to implement the code (i want to implement ad after one especific action)
