To access the survey feature, navigate to:
menu > dashboard > survey > completed tab
If you select the menu option next to the survey name, you'll be presented with an option to download the survey results. If you're accessing the feature on your phone, you'll need to email the results to yourself. If you're accessing the feature from your computer, you can download the .csv file.
The .csv file contains the name and email address of each user who completed at least one question in the survey along will their response to the question(s) they completed.
