The reporting delays were related to the database incident described here.

Due to the database timeouts, certain scheduled jobs were not run or prematurely exited.
Those processes were re-run and reports delivered later in the day.
Due to the nature of the issue, existing monitoring did not fully detect the scenario, so ProPay teams are exploring new ways to monitor for these conditions to enable more timely response for resolution.
