Thank you @weertman for bringing it to our attention. This was dependent on a setting “Show location selection in cart”. In recent version 1.6.2, this dependency has been removed. Please try the latest version and confirm if it works for you? We will embed a video to show the difference between user selection and auto selection feature. In auto selection, having show selection in cart OFF, script will auto select the location according to the priority and will consider the stocks from that inventory.
