The movingimage Webcast Consumer makes use of a networking technology called websockets, which allows for real-time updates of viewer messages.
While this technology has been in use and well supported in browsers since 2011, we are aware that some corporate networks are configured in a way that restricts or prevents the use of the technology.
If a Webcast usually uses Websockets and you open it, you will see an information panel.
If the information panel appears and the Webcast uses chat messaging, viewers must click the "refresh" button (highlighted below) to see new messages.
Note that Movingimage cannot override or bypass the Websockets restriction imposed by corporate networks. Please contact your local network administrators for more information.
