No fill admob error

Godot Version

Godot V4.3

Question

I have a problem in using admob ads on Godot 4.3. I don't know if it is something related to the Godot version or not. I have used the pongstudios plugin and another plugin but I got the same error, which is no_fill error code 3. I have tried previous versions of Godot, but I have other issues related to exporting to android when changing gradle and compile SDK versions and I couldn't solve these issues. I am using a sample app id and test unit id. The problem is for all types of ads. They failed to load.
