I have an Amazon Echo and an Echo dot. The Echo dot feeds an amplifier which is linked to ceiling speakers throughout the house and the dot is linked to the Echo. My issue is that songs will play through Spotify for most of the time but every 3rd or 4th song just stops. If I go to the app and restart the song it begins to play, but then will stop again a short time later. Is the issue with the Spotify/Echo connection? I have a good fibre broadband connection so I don't think it is that. I can leave my phone in the same place and it still stops. Is there anything I can do?
