I have created a number of skills for radio stations that have many features, more than just "play the live stream". Some users who have my skill enabled and invoke it using the exact invocation name report that instead of my skill being invoked, Alexa instead invokes TuneIn or iHeart. This is not good, since TuneIn and iHeart don't have all the features my skill has.
Some users have provided feedback to Amazon in the Alexa app, and are always told "Thank you, we'll pass that on." but nothing changes.
What can I do to convince Amazon to use my skills for the specific radio stations and stop "bypassing" my skill in deference to TuneIn and iHeart?
