I have a SharePoint 2013 on-premise portal and I have used content editor webpart to inset Yammer embed script. I have also added the following urls to IE trusted sites.
When I load the page it displays the yammer webpart with a login button and when I click on the login button it does the auth and the webpart displays feed.
If I have Yammer opened in another browser tab then the webpart automatically loads the yammer feeds (using the auth info).
What should I do to auto login and display the feeds when the webpart loads?
