When your network has a high latency (bounces a lot to associate IP addresses and names of devices) SuonO gets confused and can't find all speakers.
In those cases, we have added a feature that plays a bit more friendly during the discovery phase. To activate it follow the instructions below.
NOTE: some functionalities described below are available only in the latest releases.
Turn ON the highlighted option.
You can turn on the "Always discover Sonos network" if the app crashes on boot. That means that something that wasn't valid has been previously recorded; causing now the app to read corrupted data.
When that option is ON, a new configuration (cache) is created every time. It makes the boot of SuonO a lot slower than otherwise, so use as needed and keep it OFF if possible.
