I use my Sonos system to listen to my Audible books. I have hundreds of books so I use the search extensively, however, today I tried to search for a book while in the Audible list and Audible is not included in the drop down search. So, it defaults to TuneIn and no results are found. When did this change? Is there a setting I am not seeing? I tried looking under Amazon Music but that is specifically music not Audible. Any help would be appreciated.
