Unexpected ONE_TIME_CHARGE Refund Callback After Successful Purchase

We are using consumable in-app purchases. Starting from May 27th, we began receiving refund callbacks with the notificationType set to ONE_TIME_CHARGE immediately after users successfully completed a payment.

{
  "notificationType": "ONE_TIME_CHARGE",
  "signedPayload": "..."
}

During this period, we did not make any changes to our App release or server-side purchase handling logic.

Could this issue result in actual refunds being processed? What steps should we take to resolve this issue?

We also noticed in your changelog that a new notification type ONE_TIME_CHARGE has been introduced.

Can we safely ignore callbacks with the ONE_TIME_CHARGE notification type without affecting refund processing or user experience?
