My quote or invoice wasn't sent

Did you approve it? Korda Pro is waiting for you to reply with "Approve.” Nothing sends on its own. Check the WhatsApp chat for a draft still sitting there.

Check that Gmail is connected. Open the portal, go to Connections, and make sure Gmail is green. Emails go out from your address, so a broken Gmail connection stops them.

Check the customer's email address. Open the quote or invoice in the portal and confirm it's correct.

You can always download the PDF from the portal and send it yourself in the meantime.
