unsupportedError (error code 24): Unsupported operation

• iOS: an operation was called in UI preview mode, and the SDK answers "Operation not supported in UI preview mode" (ErrorUtils.swift).
• iOS: a feature that needs an option that is off, for example spending virtual currencies or token login without iamEnabled (Purchases.swift).
• Android: the same preview-mode refusal, and a subscription management request when no management URL exists for the current subscription.
• Android: the backend answered 7662 (product IDs malformed), which the Android SDK maps to unsupportedError and handles by not consuming the purchase (errors.kt, Backend.kt).

• Do not retry. The operation stays unsupported.
• Hide the feature in the modes where it cannot work, instead of showing an error.
• On Android, a 7662 receipt stays unconsumed on the device. Do not grant access.

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

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

On RevenueDot: RevenueDot answers HTTP 400 with code 7662 for receipts from app types it does not support yet (RevenueCat Billing, Paddle and Roku apps), and when an Android SDK asks for Amazon receipt details with a key that is not an Amazon app's. On Android that arrives as this error. Supported stores are the App Store, Mac App Store, Google Play, Amazon Appstore, Stripe and the Test Store. See 4xx or 5xx on a receipt.
