PayPal Checkout does not handle PENDING -> COMPLETED?

[niels]

WHMCS version: 8.1.3 Module: PayPal Checkout

The module works fine most of the time: it creates subscriptions, processes payments, etc. Where it fails is when it receives a payment that's pending first, completed later.

The "PAYMENT.CAPTURE.PENDING" event is processed correctly, which is to say, WHMCS recognizes this as a "Payment Pending" event in the Gateway Log.

But when the "PAYMENT.CAPTURE.COMPLETED" event comes in, WHMCS does nothing. It just lists it in the Gateway Log as "Information Only".

 

Am I doing something wrong? Or is this issue going unnoticed because it's relatively rare for a payment to go through these 2-steps. (Basically only payments that PayPal deems high-risk and wants to review first.)

I'm copying a "completed" event below, just in case someone sees anything unusual:
