If you decide to remove the product from the list of imported items, you can click the “Delete Product” button to remove it.
Once you are done with editing the product, you can click the “Save and Publish” button to publish the product on your store. Please note that this process is done in the background to avoid waiting times. This means that the item will not be instantly published. Instead, the plugin will try and publish it in the background. It might sometimes take a minute until you see the product on your store. Make sure your cronjobs are working and configured properly. For a detailed explanation on this, please click this link.
Another note that is worth mentioning is that, if you have enabled product sync, your changes will be overwritten once the product is published. This option should only be enabled when you want the process to be done automatically. You can click this link for more information regarding this.
