Hi Maria
Apologies for the hassle. An update will go out tomorrow to resolve this, we just need to do the final testing. Please, go to Appearance > Customize > Theme Design Theme Settings > Navigation, Responsive Menu must be enabled for the moment. Also, Layout > Responsive Layout must be enabled. That’ll resolve this issue. Once we’ve released the update you can disable these settings again if you wish. Basically, the drop-down script accidentally got tied to other settings that it shouldn’t have. We made a mistake with conditionals is another way to think about it.
Let me know how it goes.
