Admob do not show ad on my device.
1. i've created a admob account.
2. i've copied the publisher ID ( without "pup-" just the numbers ) into MMF2 android properties, Admob ID.
3. i've set at the frame admob properties all three options to on.
4. i've create the admob object on the frame
5. i've set an event: if click on button > show interstital.
no ads showing. what i'm doing wrong ?
