purchasesAreCompletedBy
fun purchasesAreCompletedBy(purchasesAreCompletedBy: <Error class: unknown class>): PurchasesConfiguration.Builder
An optional setting. Set this to PurchasesAreCompletedBy.MyApp if you have your own IAP implementation and want to use only RevenueCat's backend. Default is PurchasesAreCompletedBy.RevenueCat. If you are on Android and setting this to PurchasesAreCompletedBy.MyApp, you will have to acknowledge the purchases yourself.
Note: failing to acknowledge a purchase within 3 days will lead to Google Play automatically issuing a refund to the user.
