Did you ever get this to work properly? I submitted my game and Apple rejected it because of this error message. What do you have setup in your Buildbox document as the "Store Identifier". I have listed my "Store Identifier" as "com.companyname.gamename.removeads". Is this the format that you have? Thanks!
@like_a_circle It would be OK unless you have an IAP with exact the same name set as Non-Consumable and added to review.
