Here you have an example:
I have one product with 12 variants.
Each variant contains 3 images.
There are 7 pictures not linked to any variant.
This is how it looks in a mobile phone:
As you can see, the visitor has to scroll down quite much only to see the name and price of the product.
Then, when the visitor selects a variant, s/he has to scroll up again to see the picture.
...Are you facing the same issue?
Thanks.
