PowerPoint slides load into the native viewer on demand. The first time you access a presentation, the slides need to download to your device for later offline viewing. Venue Wi-Fi systems are often quickly overloaded and the venue network may be too slow to download the slides. 


We recommend accessing the PowerPoint presentations of the sessions you wish to attend when you have a good Wi-Fi connection (your hotel room, Starbucks cafes, other high-speed Wi-Fi hotspots, etc.). The slides will then be downloaded quickly and will be available offline during the session without requiring additional Internet access. 


Please note: some organizers may already pre-populate the link to the PowerPoint file while the file itself may not yet be provided by the speaker. Check back later or watch for organizer announcements when slides will become available.
