Perspective Remote Access User Authentication

Hi All

We are running Ignition 8.1.13 and are trying to using AWS EC2 as reverse proxy to allow internet access using the perspective APP. However, since the upgrade to redirect perspective app to system browser for login, we can no longer open the /idp/xxxx page on client that is accessing the project via internet. Just wondering how everyone else are coping with the use of browser for authentication in similar scenarios?
