Unfortunately not, the plugin removes all of the mobile related CSS, which is what makes everything mobile.
For some reason, the plugin isn’t running at all on your site – I can tell by looking at the HTML.
Basic CSS added by the plugin isn’t being displayed, and the calls to the mobile files which should be removed are still there.
I can login and take a look if you’d like to send me temporary admin login details to support@generatepress.com.
Let me know π
