According to the documentation for implementing admob, I need to add the com.android.vending.BILLING permission. But by adding this permission, the Google Play Store listing adds a marker claiming that the app has In-app purchases. My game does not have any in-app purchases. Upon doing research, no one else, as far as I saw, seems to use this permission when using admob. How come the documentation requires this?
I would also like to add that I and many other developers are unable to get admob to work after following the documentation. Third party plugins work perfectly but the official engine implementation does not work at all. I am requesting that Epic Games review their documentation for implementing admob.
