Hi,
I am doing paypal subscription integration and I wanted to keep track of subscription next_billing_time. After subscription is activated I tried to send api call to get subscription details to keep next_billing_time in my database however returned next_billing_time value was before last_payment like
last_payment: '2020-06-25T21:17:56Z' and next_billing_time: '2020-06-25T21:17:53Z'
so i thought i might get these details a bit later for example when payment.completed webhooks arrives however next_billing_time still did not change. I verified it in naive way and realized that next_billing_time is updated to correct date after about 20 minutes or so. I wonder whether I should keep requesting until i get updated data or is it some sandbox weird delay which will not occur on live api? if it is expected behavior how am I supposed to keep track of next_billing_time?
