The difference with Tracks is that it is responsive, so it doesn’t rely on the viewport tag to scale it to the device. There is a viewport tag added with a function outside of the header.php file, but removing it doesn’t then present Tracks at it’s desktop layout on mobile devices.
What you’ll need to do is eliminate the use of media queries completely. The media queries are what makes the styling of Tracks responsive. It will take some work, but the best way to do this would be to create a child theme (click here to download an empty one), and copy all of the CSS from Tracks’ style.css file into the child theme’s style.css file. Then, remove the line at the top of the child theme’s style.css file importing the parent theme’s stylesheet.
Lastly, you’ll need to locate each of the media queries (@media all and…) and remove them (don’t forget the trailing curly braces } ). Only with the media queries removed from the CSS will Tracks then display the same layout for all devices.
