how to copy coupon and open the site on mobile version

On mobile version the 100% work sign look too big and the coupon code is too small that can’t even see the whole coupon (I set it as click to copy, and the coupon is showing automatically). After clicking on the description u still have to manually copy the code instead of click to copy. And the newsletter option shows up on the mobile version while it’s off in the coupon settings area.

So is there a way to make the coupon section bigger? (When I set it as click to reveal it’s still a tiny dot) and also is it possible to click to copy on the mobile phone? How do I remove the newsletter on mobile version?

Thanks!
