This product was skipped because it already has a match in your other store, and the run was set to only add new products.
Why it happens
You picked "Only transfer new products". This option skips every product that already exists on the destination, so Shuttle does not create a second copy. If the run went through products you transferred or matched before, each one shows this message.
You continued a run that was set to only transfer. "Continue last run" keeps the settings of the run it continues.
Automatic transfers only create new products. A new product that already has a match in your other store is skipped.
This is a skip to protect you from duplicates. Nothing is wrong with the product.
How to fix it
If the skipped products are already in your other store and you do not need to change them, you do not have to do anything.
To update them instead:
Go to Products and click Transfer or update products.
Pick the direction: Etsy → Shopify or Shopify → Etsy.
Under What do you want to do?, pick Transfer & update products. To only refresh products that already have a match, pick Only update existing products.
Under Fields to update on duplicates, tick the fields you want Shuttle to overwrite, or tick Overwrite all fields.
Start the run.
To learn more about updates, see Updating products with Shuttle.
Still seeing it?
If a product shows this message but should not have a match in your other store, the match may be wrong. Check it, and unmatch it if needed, as shown in Matching Products & Variations. Then run the transfer again. If the message still appears after that, contact support and tell us which product it is.
