Problem wtih admob

Installed the plugin “corona Admob” once I open the app, get this message …

“”“no app id was supplied  to ads. using test app id() instead for ad network admob”"""

The Id I use is currently the departure granted by every ad Admob (ca-app-pub-xxxxxxxxxxxxxxxx) , anyone know how I can put my id of editor for this message out?
