Homepage add to cart not working

Hello, Good day!

We are having issues with adding products from the homepage. When we add a product from the homepage to the cart, it doesn’t display nor is added on the side cart. You can only see it was added once you reloaded the page.

Can you kindly help fix it or give advice/ways to fix it?
Thank you so much!
