Product variant images not changing on mobile

Hello,
I have a product that features 12 pattern variations. On desktop, when you choose a design from the dropdown the first image switches out to show the selected pattern.

However, on mobile (at least on my Google Pixel) there is no way to see what pattern you've selected. You have to scroll past all the uploaded variant images before you get to the dropdown, and when you choose a pattern there's no indication of what you've selected. Is there any way to make it more clear which is which? Ideally, to hide product variants until one is selected?
