Plugin works fine on smartphone but delet the normal menue on pc

Hi,

first thank you for this great tool.
It works fine on my android, will today try out this in a apple store for apple product.

But, when I go to the site on my pc, the menue is nit visible.
The place where the menue normally is, is blanc.

Can I fix this?

All the best Theo
