In my case, it looks like this https://recordit.co/7h2Hnokk4H. Since your changes there is a problem with loading slider. Customers also report it to us. Then the menu is unfolded and does not collapse again.
I do not know what you changed (fixed in the code), but there are more and more errors. Another one is the functioning of the shopping cart on a mobile phone. A product added to the cart shows up on the cart icon, but when you go into the cart, it shows no products. It is only when you click on the top cart that the products appear. https://gyazo.com/e3ce69882d9c94f3bf2d247ebbddaeea
