I have a custom website portal using PHP laravel but only facing one issue after applying Cloudflare that's when we add to cart some products and generate order it shows me a receipt that's mean everything is done but only on iPhone when we move back and then move forward they generate another order. So I want to know is there any caching problem after Cloudflare or something else this portal is for a reseller of my website it's not public, the front end is on WordPress and for reseller, we have backend portal separately here's the website URL:[http://example.com https://targetforarchery.com/]
