When I trying input emails to the [Bill to] box and send invoices to multiple customers. The whole system will freeze and turn to infinity loading mode.
Even worst, when you want to give up the multiple customer function and trying to send the invoice one by one, when you typing the email address, the [Bill to] box will goes to infinity loading mode again.
No matter using difference browsers, deleted cookie, turn off modem to change the IP address, the situation still not be fixed.
