Before my ads weren't showing but I decided to use the Google test ads and it showed in the app. Now I have inputted my own ad unit and it is not showing. I have not very little idea about programming.
Yes, and have more users to use your app. There is no good reason for admob to fill live ads when app only have couple user, who most likely app owners who are prohibited to click on their own ads. Hope it make senseSo, in the long run, I should publish my app on Google play?
