Sometimes while viewing orders in Listing Mirror, you can run into a banner that says:
What this means, is you've received an order for a listing that isn't in Listing Mirror but is in the marketplace. We calls these untracked listings, because Listing Mirror isn't keeping any tabs on them. This can be especially dangerous with MF QTY listings, as we are not updating the QTY on that listing at all.
To resolve this issue, deleting the listing from the marketplace and recreating the listing from Listing Mirror is your best option.
If you are unsure whether you are dealing with an untracked listing, need some assistance resolving the issue, or need some help identifying other untracked listings on your accounts, please reach out to support!
