I recently published my first game on Google Play. I integrated Unity Ads to the apk. I downloaded the game from Play Store to test if it works correctly. I started it, waited a little and Ads Button was visible and I was able to watch ads and game was working fine.
Couple of hours later I asked my friends and they told me they never saw the Ads Button on main menu. I told them to wait a little but result was same.
I know there is a daily ads limit but how come no ads are shown on a new user’s phone?
Edit: Ads are working correctly on other phones now but I don’t know what caused this problem.
