Transaction.updates emits a transaction while purchasing on the same device through product.purchase()

Hi everyone,

I'm facing a weird behaviour when purchasing an auto-renewable subscription in the sandbox environment on a real device with purchase(options:) and also listening to Transaction.updates.

I get the "You're all set. Your purchase was successful [Environment Sandbox]" alert.

I receive an update through Transaction.updates. and also a transaction from Product.PurchaseResult.

Both transactions are successfully verified and have the same transactionId. Both have PURCHASE as transactionReason.

They only differ in:

• deviceVerification
• deviceVerificationNonce
• originalPurchaseDate
• signedDate

I was not expecting to receive an update through Transaction.updates as the purchase was done on the same device.

As the documentation says, Transaction.updates emits a transaction when the system creates or updates transactions that occur outside of the app or on other devices.

Am I losing something?

Thanks for your help!
