How to assign multiple variant images to each variant while using this feature
On Variant Wizard, first assign all the images you want to link to the corresponding variants within the variant rows. Once completed, click on the 3 dots button located at the top right corner of the page and then turn the Variant Images toggle to the off position, as shown in the screenshot below.
The app will then revert the product to using the standard product image gallery layout (where all images are shown), and clicking each image will change to the correct corresponding product option.
