Google admob ads work perfectly in editor, but dont work in build

As the title says, the ads show completely fine in the editor but dont show in the built game. Like the package doesnt even exist, any part that has something to do with it breaks the game. The game was uploaded publicly 2 days ago, on admob it says ready, everything is confirmed. The code should be good too, its the same code the official documentation gives you, and its almost the same as the code i used for a previous game, and in that game the ads work without a problem. I genuinely dont know why this is happening, i need it fixed asap since we just released our game and are planning to start advertising, but we’re waiting for this to get sorted out first.
