Hey @sprod,
Does this happened after you have updated to the latest version of the theme? This could just be a caching issue. Since your are using the W3 Total Cache plugin, kindly clear your plugin caches and then in your mobile phone, clear your browser cache and test the site again. For more troubleshooting steps, this documentation may help you:
