IAP iOS configuration problem

I tried to configure a purchase in the app on my game’s Apple portal. But after requesting a review of the purchase, my product was rejected with this message.

Guideline 3.1.1 - Business - Payments - In-App Purchase


We have begun the review of your in-app purchase products but are not able to continue because you have submitted in-app purchase products for the Non-Consumable type, but you have not yet submitted an updated binary for review.

Next Steps

To resolve this issue, please upload a new binary and resubmit the in-app purchase products for review.

I use the latest stable version of Unity 2019.2.9f and the last version of Unity IAP 1.23 (Codeless).

How can I solve it?

Please elaborate as to what you mean by “configure a purchase”. Are you developing an app in Unity that is using Unity IAP? If so, and you are trying to publish your game to the app store (likely to test on TestFlight/Sandbox first) you would want to follow these directions: Unity - Manual: Configuring for Apple App Store and Mac App Store

Yes:

What do those of Apple mean with “please upload a new binary”. What is a binary?
