Answer by dengST30 for iOS In App Purchases rejection: Missing IAPs

Here is my case. All info is included in the reply to Apple.

Thanks very much for reviewing the app.On IAP a few days before, our Product Manager did not know in-app purchase products subscription well . In order to get more free user, he sent three months subscription for free to new registered usersby adjusting member date on the server side.After a lot of querying, we will use IAP App Store Promotions to get more free user, instead of changing the member date simply on the server side.We have completed in-app purchases, and will upload a new binary in App Store Connect soon.

Subscription issue, not on the iOS client Side, but on the server side.

I replied. After a while, I see the place "to submit the in app purchase" in an iOS product on App Store once.

I handled, and it disappeared. Very interesting.

I have not seen the place "to submit the in app purchase" in an iPad product on App Store.

On App Store Reviewing Issue, honest communication is very important.
