Sonos Play 1 connection issue

[teoemulation]

I bought a Sonos Play 1 and Spotify often has a lot of problems to list Sonos under available devices. Sometimes it tries to connect and then nothing, sometimes you cannot see device listed.

I tried reinstall App, it works a few the same problem. I rebooted router, Sonos Play 1, Android device.

NOTHING.

Firmware and Spotify app are updated to the latest version.

Spotify SONOS app works flawlessy, i noted that after have played with Sonos app, Spotify comes back to see the device.

I don't understand why this issue is present since months and there's no fix for this, i pay premium app and i would like to have PREMIUM support, otherwise i will be forced to switch to another music service.
