Twilio Addon

Greetings,

I recently installed Twilio Addon for Ninja Forms, But the issue is that the addon requires that when typing in the phone number that the user includes the +1 before the area code and phone number. I use the input masking feature, but it doesn’t include the +1. Does anyone know if Ninja Forms has a enable / disable button that I am not seeing or do I need to use custom CSS for this any I need to use custom CSS what would be the code I would need to use. I have also submitted a ticket to Ninja Form tech support as well.

The page I need help with: [log in to see the link]
