For the iPad, I always use SIMPL to jump to Sonos instead of a reserved join in VTPRO.? Both the Crestron Go App and even the old Mobile G Pro have a device extender in SIMPL to jump to a URL.? In this case that URL would be "sonos-2://".
For the TSW-x60, it is stuck on an older Android version that no longer is supported by Sonos.? Your only option here is to use a Sonos system with S-1 installed for the TSW-X60 Sonos app to work.? Switching to the Sonos S-2 app will break the TSW-x60 Sonos app.
