The only option here is patience.

We do need Sonos to be more transparent but it looks like all of our data like playlists and configuration  information is safe but we have now way to access it until they finish developing the app. If their estimates are correct we should be back to near normal by the end of July. Personally I think it will be more like August or September.

The new app will eventually let us manage are systems as we did with the old one. In the meantime we have to suffer the reduced functionality and wait something I’m not happy about but its clear Sonos will not be offering the alternative of reinstating the old app.
