I had an app rejected cus it said "transaction error" for the reviewer... I have done remove ads many times in the past so I know about getting the ID correct and all of that. I haven't done it before with BB 2 though... I had Buy and Use selected... that is the only thing I can think was wrong that I did. Or, are you supposed to have that selected? Or, do you have it unselected and put quantity as 1 ? Or, what? Thanks for any help.
I had the same problem. So the "Product ID" which you create & name in iTunes Connect must be inserted into the Store Identifier field in BB and not the "Apple ID" for the product.
