I created a wp website using Realistic theme a few months ago. I created a menu and a a mobile menu, and both worked fine. After some time the mobile menu is not visible anymore - not on Android or web-browsers (narrow window). At the moment I did several adjustments so I cannot be sure what caused the change (upgrade of wp and Realistic theme, upgrade of add-in Elementor, created a landing page).
I've been thorough all settings in wp and cannot understand what has gone wrong. However, I've noticed that there is a top navigation bar (linked to landing page) only visible in mobile view. Somehow this seems to replace the mobile menu.
Can I please get advice on how to solve this?

Best regards,
Malin
