The Event App now allows you to promote your Guest Speakers and to allows you to add images and GIFs to your Agenda.
Below is an example of this feature.
To add promotional material to a Session to display within your Agenda, go to Sessions (just under Insights), then select the Session you wish to customise. At the bottom of the page you will see the Event App Promotion section.
Here you will customise what you would like to add to your promotion material for your Guest Speakers and VIPs (see the above example)
Following from this. If you go back to the Agenda after you have added material, refresh the Event App, scroll down (if required) to the relevant session that you have customised and you should see your update appear (approximately a minute later).
