thanks; but then: why does my device not do play my music or tunein with the Amazon (provided) dev.kit, whereas other workshop participants had the luck that they did not run into those problems and could play the workshop examples such as play my music play npr on tunein, etc.???????? and not even the staff from the alexa amazon workshop could help!
Yep you're totally correct in the sense that there is a flag for TuneIn support. Some music playback service (including TuneIn) require certification/approval by Amazon before. Please see this related forum post for information about how to get your device tested and approved for music: https://forums.developer.amazon.com/articles/59778/launch-with-avs.html
Let us know if you have any other questions!
