I had some CSS to hide the topbar on mobile devices (max-width 979x). This has been in place for a year or so and has been working.
I upgraded to X theme version 6.1.6. When I view the site on a mobile device the topbar and its content is visible, i.e. the CSS I added is not hiding the topbar.
Within the theme options preview area of X theme, the CSS to hide the topbar is working. That is what is strange.
Can anyone help me make sure that the topbar is hidden on mobile devices?
