Thumbnails gallery style on mobile - change thumbnails per row
I really appreciate any help that people can offer for this query -
It relates to small screens sizes only - Thumbnail gallery style:
I'd like to set the gallery below so that I can force two thumbnail images per row, rather than three.
Currently the thumbnails display three wide, but each thumbnail is too tiny as a result when viewing on a smartphone.
I've already tried changing the thumbnail size from large to extra large in the customisation area, and i've also tried adding more background pixel width to each image (changing each image from 800 px to 1200 px wide), but the gallery keeps displaying three thumbnails wide on my phone regardless.
(I know this should be achievable - I offer exactly the same images and dimensions on my Etsy website, which happily displays two thumbnails wide by default).
