Have a wired S1 Sonos system running Sonosnet.
When playing something on my system and then relaunching the iOS app after a little while to change the track, the app freezes straight away when trying to reconnect and then crashes to the homescreen. Relaunching the app after crashing works.
I am still able to control the S1 volume from the iOS homescreen in between these episodes and my CR200 functions perfectly.
I have run the Network matrix to have a look at the units and everything seems ok.
Changing Sonosnet channel does not help.
Grateful for any advice.
