When you have been assigned a response you will receive an email notification. To find the response you have been assigned simply follow the below steps:
1. Head to the Autofill tab in the left-hand menu and find the correct form for which you have questions to review.
2. Open this form by clicking on the drop-down arrow next to it and clicking "in review"
3. A filtered version of the form will open where only the responses that are in review can be seen. From here you can find your name in the "Assigned User" column
4. Further filtering can be done by clicking on any name in the ribbon above the table to display on responses assigned to that user.
