The DoubleDutch platform comes preloaded with a way to gather feedback about different content at your event including agenda sessions, speakers, and exhibitors.
If this feature is on in your app configuration, attendees will see a Rate and Review section at the bottom of the item details page in the app.
Please note that this option will not show until the agenda session is over. Prior to the end of the session, the attendee will see the ability to Check-In to the session.
In addition to completing ratings in the session detail page, attendees also will see cards appear in the their activity feed that will remind them to complete the ratings (as well as other to-do's from the event). For more information on how those cards work, please refer to this article:
You can see if this feature is enabled for your app by navigating to the Setup tab in the CMS, and then looking at the "Enable Ratings" setting under the Configuration section.
