Passwordless SMS gives "Missing properties: twilio_token" error

I have configured passwordless SMS with a valid Twilio Messaging Service.

However, trying to authenticate (via Auth0 website, cURL, or my app) fails. The request to <my_domain>/passwordless/start etc. returns a 400 with the error {"error":"invalid_request","error_description":"Missing properties: twilio_token"}

I have followed all the instructions per Passwordless Connections and Passwordless Authentication with Universal Login. What am I missing?

Hi @BarthesSimpson

Please confirm your Twilio settings on your SMS connection are valid and as documented here

Warm regards.
