It's a sad day for anyone who enjoys watching cooking videos, daily vlogs, or haul videos on YouTube on Amazon's Echo Show. According to a report from The Verge, YouTube is no longer available on Amazon's smart home, touchscreen-toting speaker (or as we like to call such devices, computer). Now, if you ask Alexa to play a video from YouTube, you'll receive a message saying, "Currently, Google is not supporting YouTube on Echo Show."
