I found out a workaround on it. Maybe this will be helpful to the other users. Here’s how I do it:
1st: Remove the link URL to the whole banner itself and also remove the button inside the banner.
2nd: Create a button shortcode inside WP Bakery (to do this, you must create a temporary page and create a WP Bakery button > choose the button design and size, complete with text and link > then view the editor in classic mode > copy these code [vc_btn title=”Shop Now” shape=”round” color=”warning” size=”xs” align=”left” link=”url:your-url-link-here”])
3rd: Paste this shortcode inside the “Content” in the banner
This way, you can generate your own button with link inside the Promo Banner
