Setting up your review funnel is vitally is extremely important. The review funnel will guide your customers through where to leave reviews.
Drag & drop integrated sites from the left to the right, and in order of how you want them to appear. They will appear in the order you have set unless you choose the "list view" option. This option allows the customer to choose where they'd like to leave a review with all the options display in front of them.
Note: If you're setting up multiple locations, ensure you have the correct location toggled at the top bar.
