The first step of collecting feedback is creating a feedback form. The creation of forms is done in what we call the formbuilder. Here is a short explanation on how to locate the formbuilder and how to edit forms.
Go to "Data collection > Feedback forms".
Hover over the "Add feedback form" or an existing feedback form and select "Start from scratch" or "Edit form".
To edit a form it's also possible to click on the pencil icon at the bottom of the exiting forms.
