Alexa users can now inform meeting participants that they are running late to a meeting or event on the calendar, by saying “Alexa, I’m running late.” Customers can also specify how late they expect to be by saying “Alexa, I’ll be 10 min late for my next meeting.” Alexa will send a short email to all meeting participants, informing them of the delay after confirming the meeting the customer is referring to.
