Hi
Your template sj_revo have a problem
In megamenu 1 you have some submenus
These submenus are not shown at all in the mobile view!
You can notice it also at your demo page
demo.smartaddons.com/#sj-revo
How somene can reach those products is these submenus if they access the site from a mobile?
PS You have not updated the template to new version joomla 3.7.3 yet!!!
