I just submitted my app to the Apple for review, but unfortunately got the binary rejected with the following reason:
We noticed that your app contains a payment mechanism other than in-app purchase for digital content or to unlock features or functionality within your app, which is not appropriate for the App Store. In-app purchase is the only valid in-app payment mechanism for digital content.
I have built the app with Expo v19.0.0, and have not implemented any kind of payment mechanisms or unlock features myself. Has this problem occurred to anybody else, or do you have any suspicion on why this may be the case? Anything in Expo I need to deactivate in my app.json?
Helpful for any input!
