Sense Theme: How to change thumbnail slider media on product page to be formatted in square ratio?

Sense 2.0 theme:

I am having trouble trying to figure out how to change the thumbnail slider media below the product picture to a square ratioed format on mobile.

It seems like the media size automatically optimizes for mobile and cannot be changed, however the thumbnails look almost stretched out, are very large, and take up a lot of screen space on mobile view. I have attached a photo below for visual clarification.

Does anyone know how to change the format so I am able to have a smaller-sized slider below the product picture along with square formatted thumbnails?

Thank you

I have the same issue with the thumbnails. On the desktop version, it looks good, on mobile the thumbnails are stretched.
