Yes. When using integrations like ours, Etsy requires that all selected sizes are available in all selected colors. So if you select any discontinued variants, we can’t push the product to your store successfully.
To make sure a product is successfully pushed to your store, you will need to unselect all the discontinued variants when you are adding products through Printbest.
Tip: Look at the “Discontinued Variants” list and uncheck the colors or sizes that are shown.
