Hi,

I am using your plugin in the product details page. it was working fine for some time. but right now in admin login, it got struck to one pin code and I am not able to change it not it is showing any details for the other pin codes. Check in the incognito mode as well but no avail.

Please check these issue and provide a solution for the same.

Thanks
