 ## Known issues
 
 1. Some videos just fail, it's not clear why, they work locally. The skill just moves to the next video on the playlist, but this can mean sometimes she announces a video that doesn't play.
+2. It doesn't play video, because I don't have an Echo Show or Echo Spot to test on. If you want to buy me one, get in touch!
