purchaseCancelledError (error code 1): Purchase cancelled

• StoreKit 2: the customer dismissed the sheet. StoreKit reports StoreKitError.userCancelled and the SDK maps it here.
• StoreKit 1: SKError.paymentCancelled or overlayCancelled.
• Some iOS cancels arrive as an undocumented SKError 907 whose underlying AMSError code is 6 (payment sheet failed). The SDK treats that as a cancel as well (source).
• Android: Play Billing returns USER_CANCELED when the customer leaves the billing flow (Google docs), and the Android SDK maps it here.
• The Cancel button in the Test Store purchase dialog on Android raises it too.

• Do not retry for the customer, and do not show an error. The customer chose to stop.
• Do not grant access. Nothing was bought.
• Log it at info level, not as an error, so real failures stay visible.

// Swift
do {
  let result = try await Purchases.shared.purchase(package: package)
} catch let error as ErrorCode where error == .purchaseCancelledError {
  // handle purchase cancelled
}

// Kotlin
if (error.code == PurchasesErrorCode.PurchaseCancelledError) { /* ... */ }

On RevenueDot: RevenueDot never sees a cancelled purchase. The SDK stops before it posts a receipt to POST /v1/receipts, so no server setting changes this.
