enable pop-ups error message when I try to purchase a Zoom product

Hi,

I am trying to purchase Zoom products, however, every time I get to the final stage I get an error message asking me to enable pop-ups in my browser or use a different browser. I have enabled pop-ups in my browser and used multiple devices to try and purchase the products but I still get the same error message just before payment. Does anyone have any advice on how to get around this, please, or what the issue could be?

Thanks.
