Should somebody from the USA have their number listed like so:?
1 + area code + number ?
(Edit - I managed to get into my account again using the Authenticator app and I will make sure that I have my phone number listed in the correct format, should I ever need to reset my 2FA in the future.)
Yes. We obviously need to know which country to send the SMS to so including the country code is mandatory.
Thanks yes, I got it figured out now. My number was missing a 1 at the beginning for USA and I've now added that.
