Add to Cart issue if tab open

Hi,

I’m using your plugin with the Buy Now functionality and the Add to Cart functionality.

I’ve noticed that if I am using the Add To Cart button, it opens the Paypal page in another tab and then, if I try to add another item to the cart using the same browser window but another tab and the Add to cart tab remains open, then the item is not added to the cart.

Can you help me?

Other info:
Browser I am using is Google Chrome last version (83.0.4103.61 64 bit)

Making Short: Chrome Windows with my site tab and Add to Cart tab, both opened, the Add to cart button in my site does not add to cart the item.

The shortcode I am calling is:

[wp_paypal button=”cart” name=”aaa” amount=”000″ currency=”EUR” quantity=1 no_shipping=1 custom=”smth” button_image=”image.jpg”]

Thanks
