Hi, I hope somebody might be able to help me. I'm new to Squarespace and recently launched my first online store. I watched all the videos and read the articles, and thought I'd got everything sorted out just fine..I added a flat rate shipping option, with a nominal fee for each additional item and hit save - it now shows up when I click Shipping in the side navigation bar. However it doesn't appear to be showing up when people place an order and shipping is not being added to their total price. Instead, it seems to be giving free shipping - albeit without actually saying so - which means I'm accidentally losing money! I thought this was supposed to be an automated process? I can't find any way to make it happen manually. I've had to close my shop for the time being... Can someone advise me? (Apologies if I'm just being a newbie!) *Thank you*
