mobile navigation replacement plugins

i recently noticed that the built-in mobile nav stopped working on my posts page– you can click it, but it simply does not respond. i created a work-around for that issue, but what i’d really like to is replace the built-in mobile nav on the twenty-seventeen theme altogether. i tried WP MOBILE MENU, but couldn’t get it to work they way i need it to– i’ve got some custom code in the header for animation that WP MOBILE MENU overrides. maybe i should just let it go, but i figured i’d ask here first before doing anything drastic.

any ideas for mobile nav plugins that work well with the twenty-seventeen theme?

thanks!
