Received the following in an email but no messages in my account yet. It has been 6 days: The National Visa Center (NVC) updated the status of your immigrant visa application. Please go to the Department of State's Consular Electronic Application Center (CEAC) at https://ceac.state.gov/IV. You will need your NVC case number and invoice ID number to log into your account. Once you have logged into CEAC, please look in your message box or on the Status Chart at the bottom of the page. If NVC has feedback on any items you submitted, there will be a new message with details. If not, please simply follow the updated instructions on your Status Chart to complete your case. If any column says "Pay Now", "Invalid Doc", "Incomplete", or "Re-Opened", that means you must take action by paying a fee, submitting a form, or uploading a corrected/missing document.
