I don't know if this problem is caused by the template (Helix3) or SP Pagebuilder or just my stupidity ;-)
At my site the 'hamburger' icon is shown, but it cannot be clicked. What am I doing wrong?
Mobile menu not working

Hi there,
Thanks for contacting us. Sorry for the inconvenience. You have to keep the name of header (Header). Please check the default helix3 layout.
-Thanks
I don't understand what you mean...

OK. I made some changes, but it still doesn't seem to work :-(
I would request to you again, Please check first the Helix3 quickstart. Thanks
Hi.As far as I see, you use two sections with the same name (ID) for different devices. It is unacceptable. The ID must be unique and should not be repeated anywhere else on the page, even if the element is hidden. Remove this and use CSS to adapt Header for mobile, but not a copy.

Also repeated IDS of child elements. Worker can only be the first Header, which is located above.
