Menu not showing in mobile mode

After the latest update my menu only works on the desktop. When you shrink the window on deskstop it shows you how it should work. Ie The mobile logo in the center that takes you back to the homepage and the menu grid logo on the left side that opens out to menu items.

Not sure if you can see this screen shot.
I have tried everything on my settings, nothing changes the problem
Is this a glitch?

Thanks, Marina

It’s ok. I changed the ad placement and it seems to be working now.
