Hello, @Ekomar,
Alright, I have hidden the notice from the checkout page on mobile. Now if you click on the “Buy Now” button from mobile the notice will not appear on the page. Here is the code I added to solve your issue: https://postimg.cc/bG7BYPWL and here is the resulting image: https://postimg.cc/zy6rh94H
Please check back to your site on mobile after clearing the browser cache.
