Other Menu Button for Offcanvas Menu

Just #1 would be needed for now.

Didnt help either.

I recovered a backup where the only update available is gp premium and the menu button works as expected --> http://test.cboazpdbyk-zng4p0e296dp.p.temp-site.link/

Maybe something from https://generatepress.com/forums/topic/other-menu-button-for-offcanvas-menu/#post-1839007 isnt working anymore after the update? Something i have to change?

Fixed it with

.slideout-navigation.main-navigation:not(.is-open):not(.slideout-transition) {
display: block !important;
}

I had to change the slide change the slideout width back to 400px with

:root {
--gp-slideout-width: 400px !important;
}

but now its back to normal.

Thank you for the help!

I see. Glad you resolved it! You're welcome!
