Due to Safari's default settings, Lawline Live Webcast courses will not automatically play when entering the course center. There will be a notification at the top of the course that the course is not automatically playing (as seen below).
You will notice that the course is paused upon entering the course. To view the course, click the Play button (seen below) to begin playing the live webcast.
To enable automatic play in Safari for future Lawline courses, please update your settings to allow auto play by going to Safari > Settings for This Website > Allow Auto: switch to Allow All Auto-Play.
