Hello, @vickyprism,
1- Your SVG icons issue is resolved now, kindly check back to your site after clearing the browser cache. Here is the resulting screenshot: https://postimg.cc/ZvPPmtr1 I have set the icon by choosing the mobile layout: https://postimg.cc/LnbkMTf4
2- Regarding the shipping text I have added a custom CSS code in the theme settings check the image: https://postimg.cc/30dqKZ8X and your issue is resolved now. Please watch this video: https://streamable.com/bdx2er
3- Actually, the currency and their icons handle by the WooCommerce and WooCommerce doesn’t have the icon of the currency you set on your store it has the “NGN” for it see the image: https://postimg.cc/62TcR5kw so that’s why it appears like this I hope you get my point.
Regards 8Themes Team.
