Orbi app cannot login because verification email address is not longer valid

My Orbi app on Android can no longer login because it keeps trying to send a verification email to an email address that no longer exists.  My email address was changed on my.netgear.com months ago but the app is still trying to use the old email address.  I have cleared cache and data and reinstalled the app but it always tries to use the old dead email account to send a verification code to.  The app does not offer any other means to login.  Netgear tech support has been completely unhelpful.  Does anyone know how to fix this?
