Can't remove topic footer buttons on iOS

Development
3 
button#topic-footer-button-flag {
    display: none;
}

button#topic-footer-button-share-and-invite {
    display: none;
}

I also removed pinned and the notifications text:

#topic-footer-buttons .pinned-button {
    display: none;
}


#topic-footer-buttons {
    display: flex;
    justify-content: space-between;
    align-items: flex-start;
    
    button.create { order: -1; }
    
    .topic-notifications-button {
        margin-block: 0;
        
        .reason  {
            margin-top: 0;
            
            .text {
                display: none;
            }
        }
    }
}

@media screen and (max-width: 924px) {
    html.desktop-view #topic-footer-buttons .topic-notifications-button {
        margin-top: 1em;
    }
}

Thanks!
