Does Pause and Build plan deactivate Add to Cart button?

I am now working on Pause and Build plan and recently noticed that my Add to Cart button doesn’t work. I don’t know when did it happen exactly. Is it possible that it’s deactivated because of the current plan?

The Pause And Build plan allows you to continue developing the website at a low cost. So some features may not work as a public store. For example, you can not add a product to cart, or purchase an item.
