Second, when you pay for the DWG FastView premium or pro, you will see a popup form to collect necessary information, such as your email:
For this step, we strongly suggest you use the same email address with your account email in the billing details. If you use a different one, please make sure later you login with your DWG Fastview account email, not the billing email here. The billing email here will receive order notice and invoice. Some users use billing email to login DWG FastView even to reset password. Therefore you can't login and no account found.
Kindly pay special attention to that. Use the same email ID in registration DWG FastView and billing details. Then only 1 email can be used in login to web account, mobile app, Windows client, password reset and your shopper account.
