Fix menu at the top - mobile menu

I purchased the mobile plugin for maximenu (v 1.0.4) and is working fine. The only problem I experience is the function: 'Fix the menu at the top'. It fixes the position in the desktop mode but NOT on a mobile device - this is actually where you need it more in order to minimize the scrolling all the time. Please advise how to rectify.

Hi
please detail the problem, I 'm not sure to understand.

Hi. In the backend of Maximenu there is a setting under 'Effect options' where you can toggle 'Fix the menu at the top' on and off (yes or no).
The effect of this setting is working fine in the desktop mode.
However, when you view the website on a mobile device, (with the Mobile plugin installed)the menu does NOT stick when it comes to the top of the page (as I said - it is so much more important on a mobile device to have the menu stuck to the top instead of scrolling up and down all the time)
Thanks
