How to add "BILLING permission to your APK."
Well I have 2 apps both with in-app purchase. One is a free one with ads & theres another version for 99 cents without ads. I've published the free version & added the in-app purchases with no problem. Now I'm trying to publish the 99 cent version without ads & Google Play Dev said I have to add BILLING permission to your APK. How do I do this? I didn't get this for the free version of my app
