We recently launched a campervan store at www.redknot.co.uk and we're using the 'Beyond' theme. We have got a few initial product categories populated (e.g https://redknot.co.uk/collections/tentbox-roof-tents) but if you click into a product it is only showing the breadcrumb trail on desktop views. On mobile these disappear. Most of our traffic is mobile and I'm worried that people entering on a product page through Google have no easy way to see the parent category and the full range of products we sell.
I'm struggling to see where this is stipulated in the theme code, can anyone point me in the right direction or advise on alternative options to make it easy to return to category from a product page on mobile?
