I had a similar problem and I did the following: 1. Always add "Radio" to the end of station names. 2. Prefix the station name with something unique such as your name, to differentiate the name from another similarly named station Pandora may have as a generic station or category. For example, a station you named "Smooth Jazz Radio" might also be the name of an existing Pandora station. Rename it "Gordon's Smooth Jazz Radio". 3. In Alexa Routines, be careful to use the same case in the names as you used to name your station. For example: "Gordon's smooth jazz radio" may not be the same as ""Gordon's Smooth Jazz Radio". We are working with computers, after all. Things like that seem trivial and should be handled, frequently they are not. That could be on the Alexa side OR the Pandora side. ... View more
