It looks like the CRED button is using a different selector now. The updated CSS code that works for me:
.button.js-wpv-fields-and-views-in-toolbar,
.button.js-cred-in-toolbar,
.button.js-wpcf-access-editor-button,
#qt_content_bs_component_show_hide_button,
.mce-ico.mce-i-icon.wpv-conditional-output-icon,
.js-layout-private-add-new-top {
display:none !important;
}
