If you have enabled session feedback in schedule and/or multi-track schedule pages, you will see the results and comments in your app's analytics page.
To download and see who gave what feedback, hit the "Export Feedback" link on the top right of that section.
Please note: attribution will only be available for users who have logged into the app. To require users to identify themselves before giving feedback, change your app's privacy setting.
Only items with feedback enabled appear in the session feedback area. If you've turned feedback off for a specific schedule item, that item won't show any feedback data here — which is expected.
