Hello there,

Have you first tried to update the Magento channel in the listing software to pull in the categories? To do that:

1) If you work in the Net version > Settings -> General Settings -> Listings tab -> "Clear" button for Magento settings line.

2) If you work in the desktop/LinnLive -> from the Magento Configurators screen -> there is a drop down menu on the top panel to the right, where you can select your integrated Magento channel name -> there is "Update" button to the right of it - select the needed channel there and click the Update button to update the categories from that channel(img1).
