For the past several months, I have had problems with my Sonos system. The issues seem to be mostly with my music library and include the following:
1) Sonos app freezing. Happens on my PC and my iPad. I'm unable to stop or change what's playing.
2) Songs, particularly, longer songs, skip to next song when halfway done.
3) Persistent error messages when I try to access songs. Sometimes I have to click on a selection several times before it plays. Sometimes I'm not able to access the song at all.
4) My music library selections periodically change, having a number in front of them. Or album picture is missing.
I have entered several tickets and spoken to a Sonos support person twice. There was thought that problem could be caused by my anti virus software, but the issue is occurring on devices without firewalls. We've deleted and re-added music library at least three times. Problems are getting worse and occurring more frequently.
