Alexa can notify you if it's figured out an answer it didn't know before

When Alexa doesn't know the answer to a question, many of us just give up, or just end up looking for the answer on our phone. Not one to leave loose ends untied is Amazon, which is rolling out a feature called Answer Update on Alexa devices this week, spotted by Voicebox.

Usually when the voice assistant is stumped, it'll return an answer like "I don't know that, but I'm always learning," "I can't find the answer to the question I heard," or "Sorry, I didn't understand the question." Now if you turn on Answer Update, it'll reply with "If you ask me a question and I don't know the answer but I find out later, I'll notify you."
