Here you can choose which notifications you would like to receive. If you want to know things are ready simply tap the check box next to them and a green tick will appear. If you want to turn them off, tap them again and the green tick will disappear and you will no longer receive these notifications.
*Please note that there are also a number of notification settings controlled in Facebook via the apps area and some devices also have external notification managers. You may also need to check your app settings in your devices settings area too! If you are not receiving notifications and you have these turned on, try checking these other places listed above but get in touch with support if you continue to have problems.
