Hello,
Recently we made slight changes to the admob ads and published, i.e we added the ads in between the listview items randomly. It was working fine but soon after publishing the app in Playstore, after few hours ads stopped serving in our app.
We did not receive any policy violation email or any sort of message from Admob team & also we checked that, in other apps the ads are appearing perfectly fine, we thought it could be issue with unit, we created new ad-unit and tried, it did not work.
In admob we can see very less impressions & sometimes revenue also generates For US region only, but for india and other countries we are not seeing any impressions & we are not seeing ads also for this regions.
We have not blocked any categories in showing the ads, we have kept all the categories open.
When we debug, we started receiving error code as 3, no fill from ad server. Later we thought it could be issue with admob, we wrote email to admob team, they reverted back saying, we will get back to you ASAP.
After that we thought like it could be policy issue, hence we requested appeal & for that also no response.
We can see ads if we create new app or for other apps, but only for current app we are not able to see any ads. We are not getting the exact reason why it is happening like this.
Please help us.
Thanks
