Hello, @nhsobuz,
Thanks for the video I have understood your issue.
Now, In order to solve your issue simply go to the Dashboard >> XStore >> Theme OPtions >> Theme Custom CSS >> Global and then paste the below code at the bottom of the CSS box there.
@media(max-width:768px){.woo-variation-gallery-trigger-position-top-right{width:100% !important; height:100% !important;opacity:0 !important;}}
Then save settings and check back to your site after clearing the browser cache. The result will be appear like this: https://streamable.com/ge9og0
