Listing watch is basically the place where you could see all your listings on the marketplaces you have synced with Browntape. It will also show you how many of these listings have been uploaded on Browntape. It helps you to figure out the mapped and the unmapped listings.
Unmapped listings: The SKUs which are present on the marketplaces but not uploaded on Browntape.
You could also export an excel sheet of all these listings using the 'Download CSV' option.
