Hi Mary,
The primary navigation font size setting works as it has responsive options:

Unfortunately, the secondary navigation doesn’t have responsive options currently:

We will be adding it in when we upgrade the typography module down the road.
For now you can use this CSS to change the mobile font size:
@media (max-width: 768px) {
.secondary-navigation .main-nav ul li a, .secondary-navigation .menu-toggle, .secondary-menu-bar-items .menu-bar-item > a {
font-size: 24px;
}
}
Adding CSS: https://docs.generatepress.com/article/adding-css/
Let me know if this helps ๐
