for the cart - you use cache plugin which caches cart. Use other cache
plugins or proper configure cache plugin and disable cart page from caching

it's already answered in Themeforest. It's correct and expected, you didn't
enable ajax cart so your cart reupload page. Enable ajax in woocommerce -
settings - products

When I sorted the products and added something to the cart, it resets to the default sorting. This can be frustrating for users if they need to do the sorting every time they add to cart. video link – https://drive.google.com/file/d/1T-oD74dT_4KyPT671Ie8i_HJaUts15qX/view?usp=sharing

There’s a bug in Add to Cart, when adding something to the cart, the quantity of the other items in the cart increases too (this happens when there are existing items sa cart then I sorted to pick and add another product to cart.) video link – https://drive.google.com/file/d/1eJbr021_kiiwv1RUCyNlz7i6lRzx_9oT/view?usp=sharing

- Also can we do something about how the add to cart works? Can we not reload the page when clicking the add to cart? Like in Waltermart. If I click add to cart, it automatically adds to cart, also we can choose the quantity without reloading the page.

At first, I thought there was something wrong with the registration because it doesn't recognize the username and password that I use, but then I realized it was my fault with the the email that I entered since I already use registered it in Wordpress. My bad... when I use my wp login, my orders list was already blank. How can I mark it as items received?

- After paying, the cart still carries the items that I paid already. Also I am not automatically logged in after registering. (This only happens on desktop so I think maybe it's only an isolated case since I made a mistake for the email that I use for the registration of my first order.
