Looking for some advice to get past a road block submitting a macOS app for review with an In-App Purchase. The IAP is a non-consumable one time purchase that will unlock additional features. I've submitted a new version of the app but when I try to attache the IAP I get a warning: Unable to Submit for Review Your first non-consumable in-app purchase must be submitted with a new app version. Anyone able to shed some light? This is my first attempt at attaching an IAP and I'm stumped. Thanks, in advance.
