I found a simple solution! I was having the same problem on mobile mode.
There is no easy way to specifically turn this off for mobile, however there is a way you can turn it off on desktop, and it will reflect on mobile.
To do this, you will need to open the product page on desktop version, then you will need to select settings and select stay on product page.
I only had “stay on product page” selected for my shop. But not for the product page. Here is a video of my mobile version now.
