Twitchvertising on "[Plugin: Visual Form Builder] Conditional logic not working on Android"

Hello,

So I just implemented the VFB form, but the conditional logic isn't working on the android stock browsers. It workd on chrome and safari on the iPhone.

This is the website: http://www.nuslagen.be
And when the last dropdown is set to 2 there should appear a checkbox.

Could someone help me out?
