I am trying to set up 2 step authorization for the first time. However once I enter the emailed code into the process and go to the next step to enter my mobile number, I get an error message "Too many sms sent to this number, try again later". I don't know why that would be a thing? Is this a bug. I waited and tried later but go the same error message. It is not allowing me to set up the 2 step auth.
