Sometimes, the app's feed updates automation may miss a few deleted products during updates. When deleted products still show in your feed, you can delete the products on your products page then update your feed.
You can also use the Delete Inactive / Hidden Products button in settings to clear the deleted products then update your feed.
Finally, you can use the Delete and Fetch button on the settings page. This deletes all your products and customizations on Kudobuzz MultiChannel and fetches a new copy. This process cannot be reversed and all categorization and product edits on Kudobuzz MultiChannel will be lost.
If these options do not remove your deleted products, please let us know.
