Hello, I’m having a bug in my shop with the variation images.
Currently I’m displaying the product variations in the shop, and when I click a couple of specific products, the product page doesn’t show the image gallery, but if I refresh the browser then they appear.
Please scroll to the bottom and click over the last two shown there (link in the details).
Please deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then Activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
Otherwise, if the issue still exists then keep the 3rd party plugins deactivated and share the WP admin login details of your site so I will check and give you a possible solution.
