Moving the arrows
I decided to leave the arrows in, because as mentioned the autoplay only works on the first interaction with the carousel.
This code I got from: https://thirtyeightvisuals.com/blog/custom-arrows-testimonial-carousel-squarespace
Which also outlines more customisations to the carousel should you wish
/////TESTIMONIALS ARROWS///
.summary-carousel-pager {
position: absolute;
top: 50%;
left: 0;
transform: translateY(-50%);
width: 100% !important;
z-index: 1;
}
.sqs-gallery-design-carousel .sqs-gallery-controls .previous {
float: left;
}
.sqs-gallery-design-carousel .sqs-gallery-controls .previous,
.sqs-gallery-design-carousel .sqs-gallery-controls .next {
margin:0;
}
