Hello,
I switched to displaying the product picture gallery as vertical thumbs and noticed that on desktop the selected picture does not align with the gallery thumbs along the upper edge (screenshot attached). It is easily fixed with CSS, but since I am not sure if I have set up something incorrectly or if it is a bug, I think you should know about it.
.with-vertical-slider .swiper-slide {
align-items: initial;
}

Best regards
Martin
