I know there are a lot of questions regarding the system losing connection, but I believe I have a different situation than those I’ve seen described. My system often can’t be found on my Android phone. Sometimes I can play an album, and while it continues to play (off of my NAS) I am unable to get back in to change albums - the system is not found. However, my wife, who uses an iphone, remains connected without issue. We can be in the same room and I get a message that the Sonos system can’t be found and from her phone everything works perfectly.
