Currently EvolutionX only supports manually deleting Own Products one at a time. To delete a products first search for your product in the products listing screen. Open the item in edit mode, scroll to the bottom of the page and click the red Delete Product button.
If you need large amounts of products deleted please reach out to your Customer Success team via The Intercom chat support from within the admin and they can assist if you provide a spreadsheet of items to be deleted in bulk.
