Admob is not displaying ads

[brbr]

Hello, I have recently integrated AdMob ads into my newly developed application. I received confirmation that my AdMob account has been approved and the ads are active. However, although the test ads are displaying when I enter the test ad code, the banner ad space remains empty when I enter the banner ad code. I submitted the application for approval yesterday morning, and it has been 1.5 days since then. Should I wait a little longer for the ads to appear? Or is this situation normal? Thank you in advance. [Include relevant hyperlinks for images: https://hizliresim.com/l65r26 https://hizliresim.com/Xh1t1M]
