Hi,
Thank you for reaching out to us.
The “Availability: No” indicates the shipping availability of the shipping company, which you selected in the chrome extension, to the AliExpress product. For more details, you can see this article:?https://villatheme.com/knowledge-base/understanding-the-meaning-of-red-and-green-indicators-when-importing-products-from-aliexpress/
Regarding the error “Not found”, can you first try clearing all browser and site caches, and remove the site on the chrome extension and reauthorize it. Then import again?
If it doesn’t help, please share me the AliExpress product URL and a screenshot showing the issue you encountered when importing. Thank you.
Best regards.
