Hello @khurram virk,
During our testing, we noticed that you are using an additional plugin that replaces the default “img” tag with a “picture” tag (https://prnt.sc/-jEZ0WeQyuqm). As a result, the initialization of the vertical gallery script may not function correctly due to the modifications applied to images during the page loading process.
We recommend temporarily disabling this plugin or custom snippet that makes such modifications to check whether the issue persists. Alternatively, you can test if the problem occurs when the default gallery (horizontal type instead of vertical) is displayed on the single product page.
Best regards,
Jack Richardson
