My Question or Issue

Hi, 

I'm using Spotify with a couple Sonos Play 1, that I control through my OnePlus 5.

The problem is, I keep losing sync with the Spotify app. Sometimes the app doesn't even find my Sonos installation, although I can find it through the Sonos App on my phone. And when Spotify sees my Sonos devices, it usually lose sync after a song or two.

The problem clearly comes from my OnePlus 5 because I have no problem with my wife's device (Moto G 5). I tried all the steps displayed on this page - https://community.spotify.com/t5/Android/Android-Troubleshooting-Spotify/td-p/113082 , to no avail.

It was always problematic, but I feel like it's gotten worse since 2 weeks. I would really appreciate some help.

Thank you,

J.
