POS closings now keep a record of bank terminal responses for each payment type. You can review each request and response on the closing, and retry a terminal response that hasn't been saved yet.
Cashiers can also add a closing note and save it with the closing. A closing can't be published while a terminal response is still pending.
Before a closing is deleted, its full details and terminal history are saved to the order audit log. If that record can't be saved, the closing is not deleted.
