This video contains information about seller view in Openn offers
Below is an example of your Seller's view on their listing at all times. They are able to see all offers and values, even if you have not chosen to display the offer value to all bidders/observers.
If your seller does not see this view, it is likely they have not been set up properly as a seller for the listing
