If this is still an issue, I can post the code I use to determine if mobile (or not).

Welcome aboard, Mark! Please feel free to go ahead and post the code anyway, so that it’ll be available here for whoever needs it.

You would need to get the css html code for yourself and add in manually maybe a little research online.

There is another paid option at Serif Addons site here:https://serifaddons.com/mobile-menu-webplus.html

The Serif Addons site seems to be out of business.  You can't buy anything.  The "contact" form demo is working and looks like something I'd want but can't buy it.
