[REQUIRED] Step 2: Describe the problem

Steps to reproduce:

The problem is after integrating admob in unity project and following your online documentation, ads worked fine in Unity editor, but when I ran it on mobile phone, it can't be initialized, an ArgumentNullException occurred while MobileAds.Initialize().

Then I tried your sample Hello World, it worked just fine in Unity editor, but same exception occurred while ran on mobile phone.

Strange thing is when I switched it to mono, it worked fine on mobile phone, but il2cpp just got this exception error.

I have tried reinstall the plugin, also tried debug version, also tried .net framework and .net 2.1, but still the same problem, it seems that the code of Google mobile ads has been striped

I didn't change any code of the sample Hello World, just ran it on mobile phone(I have tried arm32 and arm64 phone), but it just got the same problem. Please help!
