1- The language you are seeing is a manual button that I created – temporary – from Appearance >>> menu
the problem with it is that it is pointing back to the home page; the actual WPML switch should be on the top left of the page on the desktop version ( which is working fine) but it is not showing on the mobile version.
The benefit of the language switch over a manual button is that it will change the language of the same page at which the visitor will change the language Ex.:
If I am at the english Cart page and change the language to Arabic (using the language switcher), it will take me to the Arabic Cart page.
but in the case of the manual button that I created temporary, it will take me back to the link I set (in this case homepage of Arabic)
2- ok thanks
