Disable on Mobile not working

Hi,

We are using the Usernoise plugin with the stated WordPress version and evolve theme. Within settings we have the disable on mobile option checked, however when we click to open the header menu in the mobile site, Usernoise’s contact form loads, taking over the screen.
How can we fix this so Usernoise doesnt load on mobile devices?
