Subscription API - APPROVED status?

[marcelopaixaor]

I had a situation where a customer made a subscription to my service, it was created with the status APPROVAL_PENDING as expected, but then transitioned to the status APPROVED. After this, it was cancelled by the user.

What I don't understand is why the status APPROVED is being used.
I saw the following explanation: https://www.paypal-community.com/t5/REST-APIs/When-creating-a-subscription-how-does-the-APPROVED-sta...

But I don't use the "start_time" parameter when creating the subscription.

Also, the APPROVED subscription GET response lacks the "billingInfo" field.

This is the GET response shortly after the transition to APPROVED status (13/08/2021 14:08:27,487 UTC😞
