AdMob Close Button Issue on iPhone Simulation

Hi everyone,

I’m experiencing an issue with AdMob ads in my Unity project where the close button does not appear when simulating on certain iPhones. I’ve attached two images , one that illustrate the issue (problem), along with a secound image showing the desired fix (solution) i need.

Could anyone provide guidance on how to resolve this UI issue? Any help would be greatly appreciated!

Thank you!
