This has nothing to do with the theme itself because it’s been in use for at least 3+ years without issues. The issue just started recently and only on mobile. Your assumption is nothing but a guess that it’s caused by the theme itself.
The theme controls the display of the menu, so…. And other things have changed since your theme was last updated.
However, here’s a good troubleshooting technique.
Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
If you can install plugins, install “Health Check”: https://wordpress.org/plugins/health-check/ On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site. You can then use its admin bar menu to turn on/off plugins and themes one at a time.
