Where are the historical results for my recurring questions?
You can access an aggregate view of a recurring poll/survey results, by clicking on the recurring series from your Results Feed.
This will take you to a full detail view of your recurring poll/survey results: you'll see a trend line of the averages of all of your votes to date (if you are on a paid plan) or the latest instance's results.
Down below the trendline/latest instance is the History table, where you'll see all historical results for your recurring poll or survey with their status and averages for each question.
To view a particular instance and detail, just click on the desired Send Date.
This will pop open a window that will show you that poll / survey's full results, including comments.
