When you are invited in to respond to a Survey, you will receive both an email invite & notifications directly in Frankli. You can get navigate to the poll directly through the notifications, from your deadlines or by clicking 'Reply' from the 'Surveys & Polls' menu item.
The open survey will appear in the 'Open Surveys' tab. You can click on the survey icon to start responding to the survey.
You can then answer or skip the questions that make up the survey. When you have responded to all the questions you will see a 'Submit' button become available. Clicking on 'Submit' will send your response.
Note: Similar to template surveys, all custom survey responses are completely anonymous in Frankli.
