I’ve tried the following code to no avail.
.button, .customer button, .shopify-challenge__button {border-radius: 100px;}
Additionally, is there a way to change the hover animation? It does a side-to-side button animation, but I’d prefer a simple color change or highlight effect.

try this 
.btn-theme {
border-radius: 50px !important;
}
Thank you! Any idea how to change the button hover animation? The animation now has the original square/rectangular edges despite the inactive button being round. Would prefer the hover to just change the button color rather than a left to right swipe color change.
.btn-theme:hover:before {
border-radius: 50px !important;
}
Try this.
