Answer 1

If using real device, check also other apps, you know they contain ads, if ads are shown. Also check individually on mobile network and on Wi-Fi.

For me, it does not show only on mobile network and in all apps. Deleting data of Google Play Services help me, and ads starts showing again. Until GPS downloads its data back. So it worked for about one minute. :-D
