Variation on Ali not available but marks as available on my store + wrong price

Hello,

These are some problems I encountered :

1. When I import a product sometimes it gives totally wrong prices (while on Ali it’s the same price for diff. variation
in my shop it gives other price for the diff. variations) .
2. Variations are marked as available when they are not available on Aliexpress.
3. Also the images in the gallery are not all imported (mostly only 1 or 2 images are imported from the 6 or 6+) when
importing to the products.
4. How can I update price when I want to change the way of shipping.

Can you tell me what to do?

Kind regards,

Patrice
