They're discontinuing support for SoundTouch Speakers. The SoundTouch App controls SoundTouch Speakers. Put two and two together...

From their announcement:

  What will no longer work:
    • Presets (preset buttons on the product and in the app)
    • Browsing or playing music services directly from the SoundTouch app
  
  Important note: Your system will no longer receive security and software updates.
  Please make sure to always use your system on a secure, private network.
