I'm trying to launch a new Mac-only app using SwiftUI and targeting macOS 12, so using the new StoreKit 2 APIs makes a ton of sense. My code for the purchases is largely based on the sample code from WWDC21, and it works really really well during local testing and when installed through TestFlight.
But the purchases never load when App Review runs the app. They've sent several screenshots, and none of the purchases are loaded and I haven no idea why.
I've made sure to select "In-App Purchase" in the "Signing & Capabilities" tab. I have created all of the purchases in App Store Connect, quadruple checked the identifiers match what the app is expecting, and made sure the purchases were submitted for review along with the app.
What else could I possibly be missing? Has anyone else had similar issues?
