What happens when you send a correction.
Copy and download buttons create a draft locally; they do not send it. “Open email draft” opens your email application, where you choose whether to send. A prepared draft is not confirmation of delivery or receipt.
Corrections are checked against the published evidence and scope. A material financial correction also requires checking dependent calculations, explanations and exported schedules. We do not promise a specific response time.
