Hello @musicaldominatrix44, welcome to the Sonos Community!
I’m sorry to hear about your experience with the Sonos App and I want you to know that we at Sonos do appreciate all feedback.
You have not mentioned any troubleshooting steps you might have taken, so allow me to ask just the main one. Have you tried uninstalling the Sonos App and then download it from our official page Download the Sonos App?
Make sure when you open the Sonos App to tap Join existing System.
If that doesn’t help, then please reach out to our Support Team for some live troubleshooting. They have tools at their disposal to help you get your Sonos system back in working order.
Feel free to reply here with any outcome and I hope you get sorted soon.
