Stuck on "Waiting on DNS propagation"

Switched over the name servers and the SSL cert still shows “Waiting on DNS propagation”. It’s been a long time, is there anything else I need to do? The site is starting to show up with an insecure warning, and my client is getting a bit anxious.

Sorry to be slow to take a look! Seems you got things fixed up in the meantime, since I see a good certificate for both www and the bare domain.
