Reply To: Variable product – choose color for product image variations setting

Hello,

Please edit each attribute item and from Product >> Attributes and remove the color preview of the values then clear cache and check back.

And the speed of changing the variations of images depends upon your server performance not our theme.

If you are still unable then deactivate all the third party plugins and provide with the admin panel login details of the website to check it myself and help you out accordingly.

Best Regards.
