1) Yes, the speaker shows up on Streaming App and it works fine with Spotify, Tidal etc., however not with Apple music on my iPhone. Even though the songs have been downloaded to my phone (not on iCloud). It shows an error msg.: "unsupported format'.
I thought it may be my router? But then all other music provider work..
2) I thought that RSB-14 works with Airplay: as DTS Play-fi web says it works: https://play-fi.com/faq/entry/how-do-i-use-airplay-with-a-play-fi-product
It even says how to set-up Airplay using the web-interface: https://play-fi.com/faq/entry/set-up-using-a-web-browser
I open a ticket with Klipsch, but no answer so far.
Thanks..
