1. Left side gallery thumbnail width. As we mentioned in our previous message, we checked your website in the latest version (126.0.2592.61) of the Edge browser on several devices, and it worked perfectly in all cases. Additionally, we are providing a video (https://monosnap.com/file/hHZyAFQIdltQn6z78MuFKZKSEkyNNB) of the product gallery functioning correctly in Edge. Unfortunately, we cannot offer a solution to a problem we cannot observe.

2. Theme settings “Gallery layout” options is not working. The product gallery layout settings differ in the theme settings compared to the frontend appearance because you are using a custom product layout (https://prnt.sc/JhnWx_7qTHKD). In this custom layout, a different gallery layout value (Thumbnails left) has been selected for the product gallery element (https://prnt.sc/qnMpftIFEVZ6). In this case, the settings from the theme options will not apply until you either disable the custom layout (https://prnt.sc/khGRVZiakvo7) or choose to inherit this specific option from the theme settings (https://prnt.sc/abiVsb318Twn).
