The Checkout is responsible for notifying the use of a promotion, while OMS is responsible for notifying cancellations (which should decrease the usage count). Duplicated notifications can occur in either scenario, and since these notifications are not properly validated, discrepancies arise and the counters can become inconsistent.\nThis issue impacts three different counters that must be fixed: (1) total promotion usage count, (2) promotion usage count per profile, and (3) total coupon usage count. The team has already released a fix for the first case (total promotion usage count), but the other two still require a fix.\n\n\n#### Simulation\n\n\n\n1. Create a promotion with a specific usage limit.\n2. Apply the promotion to multiple orders via the Checkout system.\n3. Cancel some of these orders through the OMS.\n4.\n\nObserve that the promotion usage counter may allow more orders to be created than intended.\n\n\n\nCurrently, it may not always be possible to reproduce this issue consistently, as the exact root cause of the duplicated notifications has not been determined.\n\n\n#### Workaround\n\n\nN/A"}
