In the current version, the dispute feature is implemented as a form (available to the buyer only, and for orders in Processing status) that sends a notification to the site admin. Then, the admin decides whether to issue a refund or decline the refund request. We plan to enhance disputes by adding a built-in timeline with details for both buyers and sellers.
If you use the auto-completion feature in HivePress/Settings/Orders, please note that there’s an order auto-completion period counting from the order date, or if Manual Delivery is enabled, counting from the last delivery without a requested revision.
