Paypal Express Checkout does not return Recurrent Transactions

Good afternoon people,

I have a project under test where there will be recurring monthly charge.

I am testing Paypal Express in the sandbox. The authorization works in the cart. Returning authorization also works.

But it is not working for Paypal to send recurring receipt transactions.

I set up daily recurrence to test, turn the day, debit the customer's paypal, credit the store's paypal, but in opencart there is no interaction, the subscription is still pending.

Version 3032

I test with 2302 and 3020 versions and dont working too.

You may require to use an extension for that. See in the Marketplace.
