This experiment was triggered by a small segment of users who completed the first step of checkout funnel (submitted email, name, phone number), but dropped from checkout and returned to cars catalogue 7 or more minutes later.

In the control, users didn't see any cart icon nor function to resume their checkout flow.

In the variation however, users saw a filled shopping cart icon with resume functionality. Clicking on the icon would guide and redirect users to their latest abandoned stage of their checkout flow.
