We have successfully configured and launched a News Center and posted publicly our first News Item, which is displayed properly both within Messenger News section and within News Center main URL (a custom domain properly configured following Intercom’s Custom Domains for News Center instructions).
The News Center main page loads perfectly and displays our first news Item but when clicking on the News Item title to open the News Item in a new window we land on a blank page (no 404 error, just a blank page).
