Hi there, first time posting in the community! I'm setting up my store and I want to show a banner confirming the application of a promo code when visitors come to the store from a particular URL. I've found that it seems like I should be able to do it with the Quick Announcement Bar app by looking for a keyword in the URL, but when I use the default shopify URL for applying a coupon code (store_name.com/discounts/promo_name) the end of the URL path (discount/promo_name) is disappearing on page load (before the banner loads in) and so the banner isn't finding the promo in the URL & showing up. Any suggestions? I'd prefer a free solution even if it requires a little code and some fiddling (spending money on extra apps won't hurt as much once my store is making money!), but happy to receive any help you guys have to offer!
