My Sonos is set up for TV, which appears on my daughters phone and she can control volume and everything else from there. But it does not show up in my app on my phone! We both have apple phones and we are both connected to the same WiFi. I tried to connect with my phone but the app says it can’t find the network and can’t find the Sonos system. I e had trouble from the beginning and it was so often I hired a private tech geek on an annual basis to help me; he said Sonos is the worst system and he wouldn’t use it.
