When you start using Omnivore to list on eBay it will have an affect your feedback. This FAQ walks you through impacts to individual listing feedback and your overall account feedback.

How Does It Work

Your general account feedback won't be affected, that will remain the same. That is because it is associated with your account not your listings.

The feedback link on an individual listing as shown below would be lost if you ended the listing and created a new one. 

The feedback itself would not be lost as it would still show in your overall account feedback as mentioned above. 

By ending the listing you simply lose the feedback link that is displayed within the listing.
