Hello,

You are Most Welcome.

It seems that there are some syntax errors in the Custom CSS areas in your website that’s why the CSS is not working for specific devices.

Please make sure that there are no syntax errors in the Custom CSS you added before.

Then clear cache and check back.

If the problem still occurs then provide the admin panel login details of the website to check it myself and help you out accordingly.

Regards.
