Certain consumer Alexa functionality is not supported on your Echo device because it is an enterprise device managed by K4Connect. Here is a list of things that aren’t supported:

• Knowledge (adding notes): “Alexa, add a note”
• Announcements: “Alexa, announce Good Morning”
• Shopping: “Alexa, how much is an iPad”
• To-do lists: “Alexa, make a to-do list”
