When you update the cart quantity from within the shopping cart the mini cart updates but the quantity field in the main cart does not update unless the person refreshes the page manually. Is this a known issue or is there a way to fix this? It doesnt happen in firefox.
I couldn't reproduce this on a default Magento 2 installation so it's probably something specific to your settings, theme, extensions and custom code that is causing this.
Hey,
In your browser, you can check add to cart request and check the response.
Also, you can check if there is any third party module overrides the request you call.
Thank You!
