Hi, could you provide more information on how it’s not working? For example, if there is a user who can still see the Toolbar who shouldn’t be able to.
It’s also possible that another plugin is conflicting with this one. Some plugins force the Toolbar to be hidden for certain users regardless of the settings you choose for this plugin. WooCommerce is one example. If possible, try temporarily deactivating all other plugins to see if this plugin starts working.
