I also facing the same issues Amazon campaign page not opening. I've tried various solutions, such as logging out and back in, changing browsers, accessing it on mobile and other devices, and even using a VPN. These issues are leading to advertising losses. Despite contacting customer service, I've been told that the campaign is operational on their end.
Currently, I have been facing this problem for the past 7 days.
i tried everything that a customer can do by there end. changed devices, browser, used vpn, login-logout, etc.
