Recently the eBay API we integrate with has stopped reporting many sales purchased after 9pm MST/PDT (GMT-7) until midnight later that night. As such, we are unable to process affected orders until eBay makes them discoverable to us at midnight, as we have no other way of knowing the sale occurred until then. We have reported the issue to eBay but at present do not know if this is just a technical glitch they need to clear up at their end or an intentional policy decision on their part. We'll followup here once we know more.
