Please check whether you authorized your Vobot with the Amazon prime account?

If not, please go to myvobot.com or Vobot App:

- select [settings]>>[authorized with amazon alexa], cancel the authorization.

- select again [authorized with amazon alexa], then please sign in with your Amazon prime account. After that, click OK.

If you indeed authorized your Vobot with Amazon prime account, please try:

- ask Vobot:"play xxx from prime music". (Please note that since Amazon Prime music is different from Amazon music, and thus you cannot simply ask Vobot,"play amazon music")

- go to Alexa App or alexa.amazon.com, select [music,video & books]>>>[prime music]. Then select a song from the list to see whether Vobot can play the music.
