Hi there,

For some reason, Spotify won't play on my two Play 1 speakers after I've been using it with Sonos for some time. 

Playlists keep skipping songs and saying "unable to play song, connection lost". It usually starts playing after 3-5 skipped songs. 

The speakers are wired, and have been working for a long time. 
The speakers have been rebooted. 
Reconnected Spotify to the Sonos app. 
Router reboot.

It seems that all other speakers (Arc, Sub, Play5 and one/sl) are working just fine.
