Answer 1

If you just created you ads id, it may happen. Ads normally take 5 to 24 hours to show after creation of ad id.

Answer 2

I had the same issue. your Ad unit id will not show live Ads till your app is live. Test ad will show only test ads. I had recently uploaded one app which is showing live ads after I roll-out app to the Beta-release .
