Hi All,
almost the same issue on my end as well but on different scenario
we have website on WordPress it works fine on all browser. we have a reseller dashboard build on PHP Laravel on this web application having face issue on browser back and forward button

Issue is

when we add to cart the products in our system and place order got the receipt after that we click on back and forward it's again placing order only on edge all other browser work fine

the website is https://www.minecraftdab.com/ it's work fine but we have dashboard separately, if anyone get my problem then we can schedule a zoom meeting to show the backend as well

thanks
