My site is https://flawedbyshaleen.com/ and it is built on Brooklyn theme. It has been working fine till today when we noticed this strange issue. The issue is also not replicable and happens once in a while. So when someone adds a M size of a particular product (eg. https://flawedbyshaleen.com/collections/tops/products/jaipur-top-pink-tie-dye-tank-top), what gets added in some other size (issue is not only with M size, is happening to any variation at random). Also, when we try modifying the quantity of the item in the ajax cart, the +/- icons are not increasing/decreasing the quantity.
I am not able to replicate this everytime, but we have tried it on multiple systems/devices and it happens randomly. It is not even happening repeatedly on one device, so I cannot pin-point as browser or ISP issue.
Has anyone else faced this problem? Any pointers to solve this would be very helpful!
