Placing the recommendation widget just below the images
A common request is to place the app widget just below the product images.

On the other hand, on mobile devices, placing the app directly below product images will make the app to display above the product info (product name, price...) - between product images and product price details.
This is nothing related to our app, it's simply how the theme works: the left column content is displayed above the right column content on mobile:

For that reason, you may want to use a different selector to position the app widget on mobile.
