However, we have found an issue while duplication a product, directly using “Duplicate” button of the product. So, currently in order to sell the same product, just type the name, there you will get the suggestion list, and select that from the list. We are working on the “Duplicate button”, issue.
Thank you for the quick answer ! I unfortunately don’t see the “more vendors” tab / button on the links you posted and when I go in the store, I still see multiple items with the exact same name, they didn’t group as one. Is it what you’re working to fix ?
