Twilio Device Setup Problem

I am trying to setup a Twilio Device. Following the Hubitat documentation, it says that after I have entered the SID and Token, the screen should refresh and I should be asked to enter the From and To phone numbers. However, that part of the process never happens. Why doesn't it ask me for the From and To phone numbers?

Have your tried screen refresh on your browser?

The app seems to properly refresh the screen after I ask it to save the preferences. Per your suggestion, I also manually refreshed the screen. No joy.
