User Profile

Our app is constantly being rejected because it contains 2FA to protect editing the user's profile. The user's profile can only be edited after entry of a validation code that is sent by text message to the valid US mobile number recorded for the user. Since we do not have the cell phone number of the reviewer, we cannot make that phone number part of the demo account and as a consequence the reviewer does not get the validation code and cannot get access to the profile edit functionality. The app gets rejected and even the app review bosrd continues to tell us we have to "provide demo account information" to provide access to the entire app.Obvisouly, we cannot provide the validation code, as it is app generated and an integral part of the submitted app. It is not the same as a password, but the app store reviewers don't seem to understand. Any way around this?
