Recently, most of my apps got rejected for "using non apple in-app-purchase" reason.
But none of my apps contains such behavior. I tried appeal to the app review team but they won't tell me any detail, just keep saying that I used some non-apple iap.
My app is packaged using Adobe AIR SDK version 23, and used Google Admob ANE (I even tried not using admob, just packaged with AIR, didn't work), none of them contains any iap related action.
How should I do to resolve this?
