Hmm, I'm not sure then. Does the console show anything? Also, does the AdMob dashboard show anything that could help indicate what is going on?
Unfortunately, no. There's nothing wrong from the dashboard. If there's one, there should be a report or something.
I'm trying to ask AdMob directly through the help center, but it keeps sending "Something is wrong. Please try again later" message over and over again for the last few days.

I should add more info.
When I first add the app on AdMob, it was around... 4th week of February. I wanted to take a look inside the AdMob to understand how it works back then. I was planning to publish it at the end of March, but things happen and it was finally published on April 9.
There's also the fact that not many people downloaded it. I show this game to my family and cousins and it's downloaded by 6 people. I haven't shown this to my IRL friends because I want to remain anonymous.
I think this is the problem. If there's no good traffic, it will slow to show up.
Edit:
Another answer. More or less, traffic.
