How to know if a product is imported?
When you import a product, it disappears from the supplier page to avoid duplication.
You can find it again on the Droppery product page. By going to the right of this page you can see if the product is synchronized with your site.

If it's OK, you'll get a green check, otherwise a red cross. If there's a red cross, wait, as the import may take several minutes.
If after several minutes there's nothing, you can look at the connection log and see if there's an error code.
We'll be happy to help you at info@droppery.io.
