Hi Sakar, thanks for looking into it for me. Actually, I posted this query before installing Google Fonts plugin – something I have used in some of my other projects.
After posting this query, I tired several times to track the issues but failed every time, which led me to install Google fonts.
That said, if I remove the plugin now, the issues will resurface. I really would like to find out the cause that prevents the fonts from getting rendered on mobile devices.
Since I’m already using the plugin on this site, I wonder if this post will cause further confusion with regards to my original query.
