Remove Sign Up button from mobile

Developer help

Hello - I’m on Ghost Pro / Spotlight (theme)

I’ve added code injection to remove the Sign Up button from my site: arival.ghost.io — it works on desktop, but the mobile site still displays Sign Up. Any suggestion?

.gh-subscribe-button { display: none; }

This should do it:

.gh-mobile-menu .gh-member-button {
    display: none!important;
}

That worked, thank you!
