DS-160 expiry/Drop Box Appt

I booked dropbox appointment before submitting DS-160 application. After 30 days it got expired. I paid for the appointment & the confirmation page has the expired DS-160 application id. Can I submit new DS-160 and get the application id updated? If yes, how? I don’t want to cancel my appointment.

Just start a fresh DS-160 and submit, then login to the CEAC portal and update the DS-160 in your appointment. If you need help updating DS-160 you can also call or email VFS and they can do it for you.
