My workaround was to add the following CSS to shut off the primary menu in mobile, and only turn on the secondary menu in mobile. Then I just copied the same widgets to primary and secondary (I found a plugin to make this easier). It works, but I wasn’t using the secondary menu. If I had been the subsidiary menu should work as well, but if you want to use all of them for different content you’d have to find a different way. Anyway the CSS:
@media only screen and (max-width: 767px) {
.aside {
display: none;
}
}
@media only screen and (min-width: 768px) {
#sidebar-secondary {
display: none;
}
}
