When playing music directly from the Amazon Music app on my iphone and “casting” to my Sonos speakers, I can get the music to play but I am unable to control the speakers. After it starts playing on speakers, I can’t stop it, can’t change the volume, can’t change the track, etc. Control on the Amazon music app are unavailable. Only option is to “disconnect” from the speaker, and even then the music keeps playing. Anybody else having this problem or know how to fix it? I am using both play1 and play3 speakers.
