Do you have customized branding on your Quick Base app, and are wondering where the Favorites, Search, Help, etc. icons have gone with the UI implemented this past weekend? Good news, they are still there!
The icons are white, so on a white background they will not show up. Simply update your branding so that your background color is non-white (and preferably a bit 'bold'), and you will see them again!
From Home, select Settings, then Branding. Change the background color, save, and you're all set!
