SVG Icon Not working for slide-out menu close icon

Hi,
I've just updated to GP 2.3.2, enabled SVG icons and Combine CSS options. Everything works great except the close icon in my off-canvas slide-out menu is still using the font-icon. I see in the development log this has been fixed in 2.3.2, so is it a cache issue on my server/CDN side or is there something I need to do in GP to purge this cache?. Have already tried purging the server's Critical CSS and CDN.
